  • Compsemys is an extinct genus of prehistoric turtles from the Late Cretaceous and Paleocene of North America and possibly Europe. The type species C. victa, first described by Joseph Leidy from the Hell Creek Formation in Montana in 1856, and another probable species C. russelli (originally placed in the separate genus Berruchelus), described in 2012, from Paleocene deposits in France. Its affinites have long been uncertain, but it has recently been considered to be the most basal member of Paracryptodira, despite the clade first appearing in the Late Jurassic, and is sometimes included in its own family, Compsemydidae. A revision in 2020 found Compsemydidae to be more expansive, also containing and Selenemys from the Late Jurassic of Europe, and from the Early Cretaceous of Europe. Compsemys was a moderately sized turtle, up to 30 cm (12 in) long, with a carapace covered with raised, flattened tubercles, which are not seen in any other turtle. This allows even small shell fragments to be identified as Compsemys. The skull resembles that of the alligator turtle, with a sharply hooked beak; Compsemys must have been an aquatic carnivore. The oldest known shell fragments identifiable as Compsemys are known from the Santonian stage of the Late Cretaceous in North America, while European remains are not known until the Paleocene. Compsemys is suggested to have dispersed into Europe during the early Paleocene via Greenland. The morphology of the skull suggests that Compsemys was a hypercarnivorous snapping turtle. (en)

  • Compsemys is een geslacht van uitgestorven schildpadden uit het Laat-Krijt en Paleoceen van Noord-Amerika en mogelijk Europa. De typesoort is Compsemys victa, benoemd in 1856 door Joseph Leidy op grond van resten uit de Hell Creek Formation in Montana, holotype MNHN.F.BR 9110. De geslachtsnaam betekent "bevallige schildpad". Een groot aantal verdere soorten is benoemd op basis van vondsten uit de Naciementoformatie van New Mexico, die tegenwoordig worden beschouwd als jongere synoniemen. Compsemys parva is gebaseerd op specimen USNM 6548; Compsemys puercensis op USNM 8544; Compsemys torrejonensis op USNM 8549 en Compsemys vafer op specimen USNM 6551. Een andere mogelijke soort is Compsemys russelli (in 2012 oorspronkelijk benoemd als Berruchelus), uit Paleoceen-afzettingen in Frankrijk. De affiniteiten van Compsemys zijn lang onzeker geweest, maar het is onlangs beschouwd als het meest basale lid van de Paracryptodira, ondanks dat de clade voor het eerst verscheen in het Laat-Jura, en soms wordt opgenomen in zijn eigen familie . Een herziening in 2020 vond Compsemydidae uitgebreider, met ook en Selenemys uit het Laat-Jura van Europa, en Peltochelys uit het Vroeg-Krijt van Europa. Compsemys was een schildpad van gemiddelde grootte, tot dertig centimeter lang, met een schild bedekt met verhoogde, afgeplatte knobbeltjes, die bij geen enkele andere schildpad worden gezien. Hierdoor kunnen zelfs kleine schildfragmenten worden geïdentificeerd als Compsemys. De schedel lijkt op die van de alligatorschildpad, met een scherp gebogen snavel. Compsemys moet een in het water levende carnivoor zijn geweest. De oudst bekende schildfragmenten die identificeerbaar zijn als Compsemys zijn bekend uit het Santonien van het Laat-Krijt van Noord-Amerika, terwijl Europese overblijfselen pas in het Paleoceen bekend werden. Er wordt gesuggereerd dat Compsemys zich tijdens het Vroeg-Paleoceen via Groenland in Europa heeft verspreid. De morfologie van de schedel suggereert dat Compsemys een hypercarnivore schildpad was die zijn prooi ving door snel de kaken dicht te klappen. (nl)
  • Compsemys é um gênero extinto de tartarugas pré-históricas do Cretáceo Superior e Paleoceno da América do Norte e possivelmente da Europa. A espécie-tipo C. victa, descrita pela primeira vez por Joseph Leidy da Formação Hell Creek em Montana em 1856, e outra espécie provável C. Russelli (tradicionalmente em Berruchelus), descrita em 2012, de depósitos do Paleoceno na França. Seus afinitos são incertos há muito tempo, mas recentemente foi considerado o membro mais básico de Paracryptodira, apesar do clado aparecer pela primeira vez no Jurássico Superior, e às vezes é incluído em sua própria família, . Uma revisão em 2020 descobriu que Compsemydidae era mais expansivo, também contendo e do Jurássico Superior da Europa e Peltochelys do Cretáceo Inferior da Europa. Compsemys era uma tartaruga de tamanho moderado, com até 30 cm de comprimento, com uma carapaça coberta de tubérculos elevados e achatados, que não são vistos em nenhuma outra tartaruga. Isso permite que até mesmo pequenos fragmentos de casca sejam identificados como Compsemys. O crânio assemelha-se ao da tartaruga jacaré, com o bico adunco; Compsemys deve ter sido um carnívoro aquático. Os mais antigos fragmentos de conchas identificáveis como Compsemys são conhecidos do estágio Santoniano do Cretáceo Superior na América do Norte, enquanto os restos europeus não são conhecidos até o Paleoceno. Sugere-se que o Compsemys se dispersou na Europa durante o início do Paleoceno via Groenlândia. A morfologia do crânio sugere que Compsemys era uma tartaruga hipercarnívora. (pt)
