Fossilworks was a portal which provides query, download, and analysis tools to facilitate access to the Paleobiology Database, a large relational database assembled by hundreds of paleontologists from around the world.
Fossilworks was created in 1998 by John Alroy and housed at Macquarie University. It included many analysis and data visualization tools formerly included in the Paleobiology Database. [1]
Galeocerdo is a genus of ground shark. Only a single species, G. cuvier, the tiger shark, is extant. The earliest fossils date back to the early Eocene epoch, (Ypresian), around 56–47.8 Million years ago. While historically considered a member of the requiem shark family Carcharhinidae, it is currently considered to be the only member of the family Galeocerdonidae. While this genus was historically considered diverse, including 21 extinct species, morphometric analysis conducted in 2021 suggested that the diversity of the genus included only 5 extinct species much lower than previously assumed. The oldest fossils of the extant G. cuvier date to the middle Miocene.
Viverravidae is an extinct monophyletic family of mammals from extinct superfamily Viverravoidea within the clade Carnivoramorpha, that lived from the early Palaeocene to the late Eocene in North America, Europe and Asia. They were once thought to be the earliest carnivorans and ancestral to extant ones, but now are placed outside the order Carnivora based on cranial morphology as relatives to extant carnivorans.
Ailuravus is a genus of prehistoric rodents in the family Ischyromyidae.
Eocaiman is an extinct genus of caiman containing species living from the Early Paleocene to Miocene in what is now Argentina, Itaboraí Formation of Brazil and Colombia. Eocaiman contains three described species: E. cavernensis, E. palaeocenicus, and E. itaboraiensis, and is typically recovered as one of the more basal members of Caimaninae. Notocaiman was synonymized with Eocaiman paleocenicus in 2022.
Eoscopus is an extinct genus of dissorophoidean euskelian temnospondyl in the family Micropholidae. It is known from Hamilton Quarry, a Late Carboniferous lagerstätte near Hamilton, Kansas.
Sauropleura is an extinct genus of nectridean tetrapodomorphs within the family Urocordylidae. Fossils are known from the United States and Europe. The following species are included:
Scaumenacia is an extinct genus of lungfish. It lived around the Devonian in North America alongside another prehistoric lungfish: Fleurantia. It lived from approximately 384 to 376 millions of years ago.
Isodontosaurus is an extinct genus of iguanian lizard from the Late Cretaceous of Mongolia and China. The type species is Isodontosaurus gracilis. Isodontosaurus is part of an extinct group of Late Cretaceous iguanians called Gobiguania, which is currently thought to be endemic to Mongolia.
Colubroidea is a superfamily of snakes in the clade Colubroides that includes Colubridae, with some studies splitting Colubridae into multiple families that make up Colubroidea. Historically, Colubroidea also included other caenophidian snakes such as cobras and vipers, as these snakes form a clade. However these groups are now divided into several distinct, but related, families. Zaher et al. (2009) proposed to redefine Colubroidea for colubrids and related families, while designating Colubroides as the group containing vipers and cobras as well as colubroids. The ReptileDatabase considers Colubroidea to be composed of Colubridae and the members of its sister group, Elapoidea, and does not recognize the division of Colubridae into multiple families.
Tasbacka is an extinct genus of sea turtle containing several species.
Alligator mcgrewi is an extinct species of alligator described by K.P. Schmidt in 1941. They lived in the Early Miocene period, and their range was principally in what is now Nebraska, United States. It is a small alligator with an estimated body length of 1.6 metres (5.2 ft). The Alligator mcgrewi has a unique snout, distinguishing it from other alligator species. This special feature suggests that A. mcgrewi evolved from specific environmental adaptations.
