Extract

With Jack Sepkoski's sudden death from heart failure on May 1, 1999, paleontology lost one of its most important figures. In his 25–year career, Jack published more than 70 research articles, 15 of them in this journal, and an equal number of reviews, commentaries, and abstracts. He co-edited Paleobiology (1983–86), received the Schuchert Award (1983), and served as President of the Paleontological Society (1995–96). In 1997, he was elected to the Polish Academy of Sciences and in the same year received the Medal of the University of Helsinki. Further recognition would surely have followed but for his untimely death.
