Scientists Discover Crocodile-Like Ancient Reptile in India, Its Shape is Frightening

"Scientists Discover Ancient Reptile Similar to Crocodile in India, Its Shape is Frightening"

"Samsarasuchus pamelae roamed our planet during the Early Triassic period, 251.5 million years ago."

"This ancient reptile is a member of Proterosuchidae, a small family of early archosauriforms."

"Proterosuchidae are known to have originated from the late Permian in Eastern Europe and the early Triassic in South Africa and China. These creatures are long-snouted reptiles that superficially resemble crocodiles. They range in length from 1.5 to 4 m, are adapted to hear low-frequency sounds, and likely had semi-aquatic habits. The most distinctive feature of them is the clear downward bend at the front of the upper jaw (premaxilla)."

"The origins of Archosauromorpha can be traced back to the mid to late Permian period, with some appearances in Western and Eastern Europe, the African continent, and possibly South America,"

words of the paleontologist from the University of Birmingham, Mart\u00edn Ezcurra and his colleagues.

"The presence of Permian archosauriforms suggests that the origins of the non-archosauriform archosauromorph clade must also extend back to the Permian period, although Paleozoic fossil evidence is still lacking for most of these groups (e.g., tanystropheids, rhynchosaurus, allokotosaurus, prolacertids).” “The only archosauromorph lineage with body fossils on both sides of the Permo-Triassic boundary defined by vertebrate fossils is Proterosuchidae,” they said."

“Members of this clade are characterized by a low and elongated skull with large premaxillae that are highly downward-facing, a relatively long cervical series, relatively slender limb bones, and broad plesiomorphic drivers.”

“Premaksila proterosuchid that is very large and becomes increasingly clear and distinct through ontogeny, and reciprocal social and/or sexual selection may explain the function and origin of the evolution of this peculiar feature.” Some fossil neck vertebrae of Samsarasuchus pamelae were discovered on January 18, 2015, from the upper Panchet Formation near the village of Deoli, West Bengal, India. The holotype and paratype specimens were found 10 m apart from each other at nearly the same stratigraphic level.

“We found Samsarasuchus pamelae as a member of a new clade within Proterosuchidae, named the new subfamily Chasmatosuchinae,” said the paleontologist.

“Chasmatosuchinae also includes forms from Eastern Europe, Brazil, and Australia.”

“Studies on Samsarasuchus pamelae and other early archosauriform bones from the Panchet Formation have enhanced our knowledge of proterosuchids, justifying the great potential of the Indian unit to explain the impact of the mass extinction at the end of the Permian and, in particular, on the taxonomy and phylogeny of early archosauriforms,”

“Searching for and discovering more complete new proterosuchid specimens will be very important for achieving a stronger understanding of the anatomy, taxonomy, phylogeny, and macroevolution of this clade, as well as its implications for understanding the impact of the mass extinction at the end of the Permian.”

"This finding was published in the Royal Society Open Science journal in the October 2023 edition."
