Biography edit

Carroll was an only child and grew up on a farm near Lansing, Michigan. He was introduced to paleontology by his father shortly after his fifth birthday, and by the time he was eight he had decided he wanted to be a vertebrate paleontologist. In that same year he received as a Christmas present the left femur of an Allosaurus, courtesy of Edwin H. Colbert, whom his father had told about his interest.[2][3] In his teen years his parents took him on many fossil hunting trips to Wyoming and South Dakota.

After high-school, he went to Michigan State University, where he received a B.Sc. in 1959, majoring in Geology.[3] From there he went to Harvard University where he studied biology and palaeontology under Alfred Sherwood Romer for his M.A. (1961) and Ph.D. degrees (1963); Carroll was Romer's last student.[1][4] His doctoral thesis dealt with what is now known as Dissorophoidea, a group of Paleozoic amphibians that are often considered the closest relatives of present day amphibians,[5][6][7] although they may also be stem-tetrapods if lissamphibians instead arose from within Lepospondyli.[8][9][10]

After obtaining his Ph.D., Carroll held a National Research Council (NRC) postdoctoral fellowship at Redpath Museum at McGill University in Montreal (1962-1963), and then a National Science Foundation (NSF) postdoctoral position at the Natural History Museum in London.[1] During this time, he studied tetrapod remains from the Pennsylvanian lycopod “tree stumps” at Joggins, Nova Scotia (a variety of temnospondyls, microsaurs, and basal amniotes). Most of this material was collected and first studied by Sir William Dawson, the first Principal of McGill University, in the nineteenth century.[1]

Returning from London, in 1964 Carroll joined the permanent staff of McGill University as curator of geology at the Redpath Museum and became the curator of vertebrate paleontology the following year.[2][11] At McGill, he was an assistant professor of zoology from 1964 to 1969, an associate professor of biology from 1969-1974, a full professor from 1974 onwards, and was appointed Strathcona Professor of Zoology in 1987.[1][11] From 1985 to 1991 he was director of the Redpath Museum.[11] He was an active professor until 2003, after which he was an emeritus professor.

Carroll died on April 8, 2020, in Westmount, Quebec, of complications from COVID-19.[12] He was survived by Anna DiTuri, a retired business school teacher, and his one child, David and granddaughter Juliette.

Scientific research edit

Carroll was a prolific publisher and studied numerous major topics within paleontology and vertebrate evolution. He is best known for his work addressing the origins and early evolution of amphibians[13][14][15] and reptiles[16][17][18][19][20] and published extensively on lepospondyls,[21][22][23][24] which have been variably considered as ancestors of amphibians or early reptiles. In a related vein, he also published numerous summary articles examining the evolution of tetrapods on land.[25][26][27][28] He is also well published on marine reptiles.[29][30][31][32][33]

He also published a number of books, including Vertebrate Paleontology and Evolution (1988),[34] which remains a seminal textbook, Patterns and Processes of Vertebrate Evolution (1997),[35] and The Rise of Amphibians: 365 Million Years of Evolution (2009).[36] He coauthored another textbook, Paleontology (1998),[37] and a volume of the Handbook of Paleoherpetology on lepospondyls (1998).[38] He also edited a volume of the Amphibian Biology series on the evolutionary history of amphibians (2000).[39]

Carroll contributed to naming an extensive number of new species, outlined below:

Several taxa are named after Carroll, including the teleost fish Mahengecharax carrolli, the 'microsaurs' Bolterpeton carrolli (now a synonym of the parareptile Delorhynchus) and Carrolla craddocki, and the captorhinid Opisthodontosaurus carrolli. He was honored with a festschrift in 2003.[1]

Carroll was awarded a large number of awards, including the Charles Schuchert Award of the Paleontological Society (1978), of which he was one of the first recipients, the Elkanah Billings Medal of the Geological Association of Canada (1991), the Willet G. Miller Medal of the Royal Society of Canada (2001), of which he was made an honorary member in 1993, and the Romer-Simpson Medal of the Society of Vertebrate Paleontology (2004), the society's most prestigious honor,[4] and was appointed a member of the Order of Canada (2019).[51][52] Carroll also served as the president of the Society of Vertebrate Paleontology from 1982 to 1983.[53] The Canadian Society of Vertebrate Paleontology's Carroll Prize is named after Carroll.[54]

Carroll is often credited with being the "father of Canadian vertebrate paleontology"[4] because many contemporary Canadian paleontologists can trace their graduate training back to him. Carroll supervised numerous graduate students, many of whom went on to lead their own successful research labs, including Jason Anderson (University of Calgary), Michael Caldwell (University of Alberta), Philip Currie (University of Alberta), and Robert Reisz (University of Toronto).

and then a National Science Foundation NSF postdoctoral position at the Natural History Museum in London 1 During this time he studied tetrapod remains from the Pennsylvanian lycopod tree stumps at Joggins Nova Scotia a variety of temnospondyls microsaurs and basal amniotes Most of this material was collected and first studied by Sir William Dawson the first Principal of McGill University in the nineteenth century 1 Returning from London in 1964 Carroll joined the permanent staff of McGill University as curator of geology at the Redpath Museum and became the curator of vertebrate paleontology the following year 2 11 At McGill he was an assistant professor of zoology from 1964 to 1969 an associate professor of biology from 1969 1974 a full professor from 1974 onwards and was appointed Strathcona Professor of Zoology in 1987 1 11 From 1985 to 1991 he was director of the Redpath Museum 11 He was an active professor until 2003 after which he was an emeritus professor Carroll died on April 8 2020 in Westmount Quebec of complications from COVID 19 12 He was survived by Anna DiTuri a retired business school teacher and his one child David and granddaughter Juliette Scientific research editCarroll was a prolific publisher and studied numerous major topics within paleontology and vertebrate evolution He is best known for his work addressing the origins and early evolution of amphibians 13 14 15 and reptiles 16 17 18 19 20 and published extensively on lepospondyls 21 22 23 24 which have been variably considered as ancestors of amphibians or early reptiles In a related vein he also published numerous summary articles examining the evolution of tetrapods on land 25 26 27 28 He is also well published on marine reptiles 29 30 31 32 33 He also published a number of books including Vertebrate Paleontology and Evolution 1988 34 which remains a seminal textbook Patterns and Processes of Vertebrate Evolution 1997 35 and The Rise of Amphibians 365 Million Years of Evolution 2009 36 He coauthored another textbook Paleontology 1998 37 and a volume of the Handbook of Paleoherpetology on lepospondyls 1998 38 He also edited a volume of the Amphibian Biology series on the evolutionary history of amphibians 2000 39 Carroll contributed to naming an extensive number of new species outlined below Year Taxon Authors 1991 Utaherpeton franklini gen et sp nov Carroll

Opisthodontosaurus carrolli He was honored with a festschrift in 2003 1 Carroll was awarded a large number of awards including the Charles Schuchert Award of the Paleontological Society 1978 of which he was one of the first recipients the Elkanah Billings Medal of the Geological Association of Canada 1991 the Willet G Miller Medal of the Royal Society of Canada 2001 of which he was made an honorary member in 1993 and the Romer Simpson Medal of the Society of Vertebrate Paleontology 2004 the society s most prestigious honor 4 and was appointed a member of the Order of Canada 2019 51 52 Carroll also served as the president of the Society of Vertebrate Paleontology from 1982 to 1983 53 The Canadian Society of Vertebrate Paleontology s Carroll Prize is named after Carroll 54 Carroll is often credited with being the father of Canadian vertebrate paleontology 4 because many contemporary Canadian paleontologists can trace their graduate training back to him Carroll supervised numerous graduate students many of whom went on to lead their own successful research labs including Jason Anderson University of Calgary Michael Caldwell University of Alberta Philip Currie University of
