Additionally, based on the geological age of its fossil remains, Cryodrakon would have been one of the oldest known North American azhdarchids. [2] In 2021, American paleontologist Brian Andres performed a phylogenetic analysis on Quetzalcoatlus, in which he included Cryodrakon.
These were the first scientifically described pterosaur fossils from North America. [7] November – December 31st. Sir Richard Owen expressed astonishment at the North American discovery of pterosaurs exceeding the size of warm-blooded birds and mammals, given his interpretation of the group as typical cold blooded reptiles.

The first reasonably correct identification of a vertebrate fossil in North America was made in 1725, at a South Carolina plantation called Stono. [7] There slaves had uncovered several large fossil teeth while digging in a swamp. The slaves unanimously identified the teeth as elephant molars, which they would have recognized from life in Africa.
This bone constituted at the time the oldest pterosaur remains found, recognized, and described from North America. [2] Othniel Charles Marsh first named it as a species of Pterodactylus: [3] P. montanus, the specific name meaning "from the mountains" in Latin, but soon changed his mind and gave it a new generic name.
In 2014, physician Pedro Lucas Porcela Aurelio found the fossil in the town of Paraiso do Sul in Brazil's southernmost Rio Grande do Sul state. He donated it to a local university in 2021, kicking ...
Fossils of Tawa-like dinosaurs have also been found in South America, which has important indications about paleogeography. During the Early Jurassic Period, dinosaurs such as Dilophosaurus, Anchisaurus, Coelophysis (formerly known as Megapnosaurus), and the early thyreophoran Scutellosaurus lived in North America.
A rare dinosaur bone bed containing 115-million-year-old fossils has been unearthed in Maryland, officials and experts say. During a dig at Prince George’s County’s Dinosaur Park in Laurel in ...
