The Late Triassic fauna of the Lossiemouth Sandstone Formation (LSF) from the Elgin area, Scotland, has been pivotal in expanding our understanding of Triassic terrestrial tetrapods. Frustratingly, due to their odd preservation, interpretations of the Elgin Triassic specimens have relied on destructive moulding techniques, which only provide incomplete, and potentially distorted, information. Here, we show that micro-computed tomography (μCT) could revitalise the study of this important assemblage. We describe a long-neglected specimen that was originally identified as a pseudosuchian archosaur, Ornithosuchus woodwardi. μCT scans revealed dozens of bones belonging to at least two taxa: a small-bodied pseudosuchian and a specimen of the procolophonid Leptopleuron lacertinum. The pseudosuchian skeleton possesses a combination of characters that are unique to the clade Erpetosuchidae. As a basis for investigating the phylogenetic relationships of this new specimen, we reviewed the anatomy, taxonomy and systematics of other erpetosuchid specimens from the LSF (all previously referred to Erpetosuchus). Unfortunately, due to the differing representation of the skeleton in the available Erpetosuchus specimens, we cannot determine whether the erpetosuchid specimen we describe here belongs to Erpetosuchus granti (to which we show it is closely related) or if it represents a distinct new taxon. Nevertheless, our results shed light on rarely preserved details of erpetosuchid anatomy. Finally, the unanticipated new information extracted from both previously studied and neglected specimens suggests that fossil remains may be much more widely distributed in the Elgin quarries than previously recognised, and that the richness of the LSF might have been underestimated.

This article explores the spatial history and ‘afterlives’ of Galway jail, where an innocent man, Myles Joyce, was executed in 1882 following his conviction for the Maamtrasna murders; in 2018 he was formally pardoned by President Michael D. Higgins. The article traces how the political and cultural meanings of this incident were instrumentalised in the building of Ireland's last Catholic cathedral on the site of the former Galway jail. It analyses how the site was depicted – in different ways and at different moments – as one of justice, of injustice, of triumph, and of redemption. It investigates how these different legacies were instrumentalised – or at times ignored – by Irish nationalists and later by the Catholic bishop of Galway, Michael Browne. It uses Joyce's execution to explore the site's legacy, an incident that at times dominated its representations but at other moments faded from prominence. The article situates the former jail site within theoretical writings on memorialisation, ‘difficult’ heritage, and studies of architectural demolition, while also commenting on mid twentieth-century Irish Catholic politics and culture.

This article explores the intellectual culture of Catholic architectural production in 1950s Ireland through the study of a church-building project in rural West Cork. It analyses the phenomenon of the Irish ‘church-building priest’ in terms of their socio-economic background, fundraising abilities, and position within rural communities – in the context of significant rural emigration and economic stagnation. It also considers the role that the Irish countryside played in conditioning clerical understandings of architectural style and taste, and priests’ political readings of the rural landscape. Furthermore, it explores the phenomenon of Marianism in church design and ornamentation around the time of the international ‘Marian Year’ of 1954, and the political meanings of the rhetoric employed by clerics at church consecration ceremonies. The article concludes with reflections on social and economic aspects of Irish rural life and religious expression in a decade primarily understood as one of cultural insularity and conservative Catholicism.

The Kilmaluag Formation on the Isle of Skye, Scotland, provides one of the richest Mesozoic vertebrate fossil assemblages in the UK, and is among the richest globally for Middle Jurassic tetrapods. Since its discovery in 1971, this assemblage has predominantly yielded small-bodied tetrapods, including salamanders, choristoderes, lepidosaurs, turtles, crocodylomorphs, pterosaurs, dinosaurs, non-mammalian cynodonts and mammals, alongside abundant fish and invertebrates. It is protected as a Site of Special Scientific Interest and by Nature Conservancy Order. Unlike contemporaneous localities from England, this assemblage yields associated partial skeletons, providing unprecedented new data. We present a comprehensive updated overview of the Kilmaluag Formation, including its geology and the fossil collections made to date, with evidence of several species occurrences presented here for the first time. We place the vertebrate faunal assemblage in an international context through comparisons with relevant contemporaneous localities from the UK, Europe, Africa, Asia and the US. This wealth of material reveals the Kilmaluag Formation as a vertebrate fossil assemblage of global significance, both in terms of understanding Middle Jurassic faunal composition and the completeness of specimens, with implications for the early evolutionary histories of mammals, squamates and amphibians.

A major town planning dispute between church and state in Galway in the 1940s over the location for a new school provides a lens for rethinking Ireland's distinctive engagement with modernity. Using town planning and urban governance lenses, this article argues that existing scholarship on the postwar Irish Catholic Church overstates its hegemonic power. In analyzing the dispute, it critiques the undue focus within European town-planning studies on the state and on the supposedly “rational” agendas of mid-century planners, showing instead how religious entities forged parallel paths of urban modernity and urban governance. It thus adds an Irish and an urban-planning dimension to existing debates within religious history about urbanization and secularization, showing how adaptive the Irish Catholic Church was to high modernity. Finally, with its focus on a school building, it brings a built environment angle into studies of education policy in Ireland. In seeking to revisit major historiographical debates within town planning, religious history, and studies of urban modernity, the article makes extensive use of the recently opened papers of Bishop Michael Browne of Galway, a noted public intellectual within the Irish Catholic Church and a European expert on canon law.

Whether monozygotic (MZ) and dizygotic (DZ) twins differ from each other in a variety of phenotypes is important for genetic twin modeling and for inferences made from twin studies in general. We analyzed whether there were differences in individual, maternal and paternal education between MZ and DZ twins in a large pooled dataset. Information was gathered on individual education for 218,362 adult twins from 27 twin cohorts (53% females; 39% MZ twins), and on maternal and paternal education for 147,315 and 143,056 twins respectively, from 28 twin cohorts (52% females; 38% MZ twins). Together, we had information on individual or parental education from 42 twin cohorts representing 19 countries. The original education classifications were transformed to education years and analyzed using linear regression models. Overall, MZ males had 0.26 (95% CI [0.21, 0.31]) years and MZ females 0.17 (95% CI [0.12, 0.21]) years longer education than DZ twins. The zygosity difference became smaller in more recent birth cohorts for both males and females. Parental education was somewhat longer for fathers of DZ twins in cohorts born in 1990–1999 (0.16 years, 95% CI [0.08, 0.25]) and 2000 or later (0.11 years, 95% CI [0.00, 0.22]), compared with fathers of MZ twins. The results show that the years of both individual and parental education are largely similar in MZ and DZ twins. We suggest that the socio-economic differences between MZ and DZ twins are so small that inferences based upon genetic modeling of twin data are not affected.

While the introduction of central-government inspectors for prisons in a British act of 1835 has been seen as a key Whig achievement of the 1830s, the Irish precedent enacted by Charles Grant, a liberal Tory chief secretary, in the early 1820s, has gone unnoticed by scholars. The article sets out to trace the Irish prefiguring of this measure and, in the process, to consider prison reform in the United Kingdom in the early nineteenth century in a more transnational manner. A new analysis of the critical years between 1823 and 1835 in both Britain and Ireland based on a detailed examination of parliamentary inquiries and legislation shows how developments in the two countries overlapped and how reforms in one jurisdiction affected the other. This article explores the channels through which this exchange of knowledge and ideas occurred – both in parliament and through interlinked penal-reform philanthropic societies in both countries. This article also highlights inadequacies with the theory supported by some scholars that Ireland functioned as a laboratory for British social reform at this time, and instead suggests a more fluid exchange of ideas in both directions at different times.

A trend toward greater body size in dizygotic (DZ) than in monozygotic (MZ) twins has been suggested by some but not all studies, and this difference may also vary by age. We analyzed zygosity differences in mean values and variances of height and body mass index (BMI) among male and female twins from infancy to old age. Data were derived from an international database of 54 twin cohorts participating in the COllaborative project of Development of Anthropometrical measures in Twins (CODATwins), and included 842,951 height and BMI measurements from twins aged 1 to 102 years. The results showed that DZ twins were consistently taller than MZ twins, with differences of up to 2.0 cm in childhood and adolescence and up to 0.9 cm in adulthood. Similarly, a greater mean BMI of up to 0.3 kg/m2 in childhood and adolescence and up to 0.2 kg/m2 in adulthood was observed in DZ twins, although the pattern was less consistent. DZ twins presented up to 1.7% greater height and 1.9% greater BMI than MZ twins; these percentage differences were largest in middle and late childhood and decreased with age in both sexes. The variance of height was similar in MZ and DZ twins at most ages. In contrast, the variance of BMI was significantly higher in DZ than in MZ twins, particularly in childhood. In conclusion, DZ twins were generally taller and had greater BMI than MZ twins, but the differences decreased with age in both sexes.

For over 100 years, the genetics of human anthropometric traits has attracted scientific interest. In particular, height and body mass index (BMI, calculated as kg/m2) have been under intensive genetic research. However, it is still largely unknown whether and how heritability estimates vary between human populations. Opportunities to address this question have increased recently because of the establishment of many new twin cohorts and the increasing accumulation of data in established twin cohorts. We started a new research project to analyze systematically (1) the variation of heritability estimates of height, BMI and their trajectories over the life course between birth cohorts, ethnicities and countries, and (2) to study the effects of birth-related factors, education and smoking on these anthropometric traits and whether these effects vary between twin cohorts. We identified 67 twin projects, including both monozygotic (MZ) and dizygotic (DZ) twins, using various sources. We asked for individual level data on height and weight including repeated measurements, birth related traits, background variables, education and smoking. By the end of 2014, 48 projects participated. Together, we have 893,458 height and weight measures (52% females) from 434,723 twin individuals, including 201,192 complete twin pairs (40% monozygotic, 40% same-sex dizygotic and 20% opposite-sex dizygotic) representing 22 countries. This project demonstrates that large-scale international twin studies are feasible and can promote the use of existing data for novel research purposes.

It is the aim, in this article, to identify the reasons why certain designs for courthouses in early-nineteenth-century Ireland remained unexecuted, and to do so by analysing surviving drawings and placing them in the political context at this time of Irish local government and of the efforts of Westminster politicians to institute reform. The funding and erection of courthouses were managed by grand juries, an archaic form of local government which gave few rights to smaller taxpayers and was widely perceived as an unaccountable institution associated with the ancien régime. In addition to hosting court sittings, courthouses were used by these grand juries for their private meetings and functions. By exploring the agendas and pretensions of these bodies, and by looking at the fluctuating availability of funding sources that were needed to initiate building work, I will argue through a series of Irish case studies that a renewed focus on elite patronage and its associated politics allows a new insight into courthouse building, which places less emphasis than is often the case on, for example, the role played by the changing legal profession in the architectural development of the courthouse.

In nineteenth-century Ireland, courthouses demarcated the visible and tangible presence in the urban landscape of the law and state-sanctioned justice. Laws passed by the Irish parliament and then, after its abolition in 1800, by the Westminster government, were enforced in assize courthouses by travelling judges on established ‘circuits’, visiting each city or county town twice a year (in the spring and summer). These judges travelled with great splendour through the countryside, and were welcomed by a high sheriff at the county border and escorted with military pageantry, ritual, and procession to their destination.

Parringtonia gracilis Huene, 1939 is represented by both cranial and postcranial material collected from the lower Middle Triassic (Anisian) Lifua Member of the Manda beds in southwestern Tanzania. This aberrant taxon was previously proposed to have affinities with pseudosuchian archosaurs, and specifically with the enigmatic Erpetosuchus granti from the Upper Triassic of Scotland. Here, we confirm the close affinities of Parringtonia gracilis and Erpetosuchus granti based on the following unambiguous synapomorphies: mediolaterally expanded posterior portion of the maxilla, alveoli present only in the anterior half of the maxilla, and absence of tooth serrations. Furthermore, the two taxa share osteoderms with deep sculpturing, a deep fossa on the dorsal margin of the neural spines and a heavily waisted shaft of the scapula. We added both Parringtonia gracilis and Erpetosuchus granti into a comprehensive phylogenetic analysis of early archosaurs and found that these taxa are clearly referable to Archosauria but that relationships are poorly resolved at the base of this clade. However, our analysis demonstrates that Erpetosuchus granti is not closely related to Crocodylomorpha, as has been hypothesized previously. The Erpetosuchidae are a clade of small-bodied archosaurs that have a poor fossil record but have members from both northern and southern Pangaea, ranging temporally from the Middle to Late Triassic. Thus, Erpetosuchidae is part of the early archosaurian radiation.

Fossils of Mesozoic terrestrial vertebrates from Lithuania and the wider East Baltic region of Europe have previously been unknown. We here report the first Mesozoic terrestrial vertebrate fossils from Lithuania: two premaxillary specimens and three teeth that belong to Phytosauria, a common clade of semiaquatic Triassic archosauriforms. These specimens represent an uncrested phytosaur, similar to several species within the genera Paleorhinus, Parasuchus, Rutiodon and Nicrosaurus. Because phytosaurs are currently only known from the Upper Triassic, their discovery in northwestern Lithuania (the Šaltiškiai clay-pit) suggests that at least part of the Triassic succession in this region is Late Triassic in age, and is not solely Early Triassic as has been previously considered. The new specimens are among the most northerly occurrences of phytosaurs in the Late Triassic, as Lithuania was approximately 7–10° further north than classic phytosaur-bearing localities in nearby Germany and Poland, and as much as 40° further north than the best-sampled phytosaur localities in North America. The far northerly occurrence of the Lithuanian fossils prompts a review of phytosaur biogeography and distribution, which suggests that these predators were widely distributed in the Triassic monsoonal belt but rarer in more arid regions.

Conjugated linoleic acid (CLA) reduces mammary milk fat synthesis in a dose-dependent manner. Our objective was to determine the effects of lipid-encapsulated CLA (LE-CLA) supplementation on milk production, reproductive performance and metabolic responses in lactating dairy cows fed a grass silage-based diet. Seventy-two Holstein-Friesian cows (32 primiparous and 40 multiparous) were used in a completely randomized block design. Cows received either 80 g of LE-CLA daily or 60 g of calcium salts of palm fatty acids daily (control) from parturition until 60 days in milk. LE-CLA contained a 50:50 mix of cis-9,trans-11 CLA and trans-10,cis-12 CLA, resulting in a daily intake of 6 g of each isomer. Milk production and dry matter intake were recorded daily, and blood samples were collected 3-times a week. Blood samples were analysed for circulating concentrations of glucose, non-esterified fatty acids (NEFA), β-hydroxybutyrate (BHBA), insulin and insulin-like growth factor-I (IGF-I). Progesterone was measured in blood samples collected after the first post-partum insemination. Ovarian ultrasound examinations commenced at 8–10 d post partum and were carried out 3-times a week until first ovulation. LE-CLA treatment resulted in decreased milk fat concentration, with consequent improvements in energy balance and body condition score (BCS). The peak concentration of NEFA in blood was reduced by LE-CLA, but circulating concentrations of insulin, glucose, IGF-I, BHBA and progesterone were not affected. There was no effect of LE-CLA supplementation on the post-partum interval to first ovulation. Services per conception tended to be reduced. The reduction in milk energy output and improvement in energy status and BCS in LE-CLA-supplemented cows provides a strong rationale for further studies with greater cow numbers to test effects on reproductive performance.
