Approximately 95 million years ago, along the coast of the western inland seas in what is now southwestern Montana, suggests a small crocodile-like creature with strange, covered teeth drilled.
In a new study, the first creature ever discovered – a teenage clock called Elton, measured about 2 feet (60 centimeters) long from the nose to the tip of its tail. Elton’s fossilized body was discovered in 2021 during an organized excavation of the black leaf geological layer.

According to the statement, the first fossil Allen was Elton’s skull, only 2 inches (5 cm) long and embedded in the rock. Allen showed a miniature skull to David Balilylickio, professor of paleontology, taphonomy and existence at Montana State University. He quickly realized the importance of fossils.
“After digging up, Dr. Varricchio told me why he was so excited the day he found the first specimen,” Allen said. “It was a very visible anatomy to explore, and he found it to be a small, tiny crocodile skull, completely clear and preserved. It was something special.”
Elton belonged to a crocodile-like creature that researchers didn’t know existed before, or a now-creative family of crocodile-shaped crocodile-shaped. This family, called the Wannchampsidae, is located within the lineage neosuchia, which contains all modern crocodiles and their closest relatives. Its members lived in North America during the Cretaceous period, and they were much smaller than other Neostian crocodiles. If Elton had survived to adulthood, he would have grown to 3 feet (90 cm) in length, according to the statement.
Neoschians are usually semiaquatic or marine carniballs with simple cone-shaped teeth, but not Elton. According to the statement, he and the members of the new species had a differently shaped assortment of teeth, including pods and other special tusks, for a new species named Ticarisquis Xenodentes.
Elton and his kind also live in the land, and they probably created a burrow in the ground, the statement said, probably based on how dense Elton’s bones Allen and his colleagues analyzed them.
Shortly after finding Elton’s skull, Allen went back and gathered bags of surrounding sediment to seek more clues about the animal. He sifted through hours of soil, extracted bone fragments, and gradually reconstructed the Tikaliskos skeleton. He worked with classmate Dane Johnson, a paleontology researcher and field specialist at the Rockies Museum in Montana. This often influenced the name Elton, along with the song of Elton John’s 1972 song “Crocodile Rock.”
To take a clear picture of the fossil, Allen performed a CT scan. This helped to distinguish between rocks and rock masses that were still stuck on Elton’s body. “Harrison worked very hard to reconstruct animals digitally, but it came out beautifully,” Varricchio, co-author of the new study, said in a statement.
A detailed description and photograph of T. Xenodentes, as well as a discussion of the location of new species in evolutionary trees, is included in a study published in Vertebrate Paleontology on September 22nd. In particular, researchers highlight a family of ancient crocodile subjects known as the Atopasauriaceae, previously discovered in Eurasia and appearing to be Eltons.
“In the same period, similar environmental conditions, prey availability, and who knows, suggest that convergent evolution can be seen between the two distant related groups.
