Ancient Crocodile Fossils Reveal New Montana Species
Summary of the Newly Discovered Ancient Crocodile, Thikarisuchus xenodentes
This article details the discovery of a new species of ancient crocodile relative, Thikarisuchus xenodentes, from fossils found in Montana, USA. Here’s a breakdown of the key information:
* Discovery Location: Blackleaf Formation near Dillon,montana. Fossils were found in the summer of 2021.
* Age: Approximately 95 million years old.
* Size: Relatively small for a crocodyliform. Estimated adult length of no more than 90 cm (about 3 feet), based on a fossil representing 60cm from nose to tail.
* Lifestyle: Unlike most ancient crocodile relatives that lived in water, Thikarisuchus xenodentes was terrestrial (land-dwelling).
* Diet: Varied and specialized teeth suggest a diet of insects, small animals, and plants.
* Unique Anatomy: Possesses a unique anatomy that warrants its classification into a new Crocodyliform family: Wannchampsidae.
* Family Connections: Wannchampsidae shares similarities with the Atopasauridae family from Eurasia, as well as other Crocodyliform groups in Africa and South America, suggesting convergent evolution due to similar environmental pressures.
* Fossil Arrangement: The concentrated arrangement of bones suggests the animal likely died in its burrow.
* Significance: This discovery is only the second vertebrate fossil found at this location and expands our understanding of ancient crocodile evolution and distribution.
In essence, Thikarisuchus xenodentes represents a unique and previously unknown branch in the crocodile family tree, offering insights into the diversity and adaptability of these ancient reptiles.
