Paleothyris was a primitive reptile that lived during the Carboniferous period, perhaps around 300 million years
ago in North America (fossils of the animal were discovered
in Nova Scotia, Canada). At the time of writing,
it is probably the earliest known amniote (tetrapod vertebrates with a terrestrially adapted egg - the group which
includes reptiles, birds, mammal-like reptiles, and mammals).
Paleothyris was about 1 foot (30 centimeters) long and outwardly resembled a lizard (the animal's colors are not
known, and the colors shown in the picture above are however speculations based on modern lizards). However anatomically,
Paleothyris did not have the openings in its skull (fenestrae) that are found in lizards and most other amniotes
(today, the only surviving amniotes without fenestrae are turtles and tortoises).
Paleothyris had large eyes aand is therefore thought to have been a noctural (at night). It had sharp teeth, and scientists speculate it probably lived on forest floors. It is thought that perhaps it hunted insects, and, maybe other small animals as well.

High Quality Content by WIKIPEDIA articles! Paleothyris was a small, agile, anapsid reptile which lived in the Middle Pennsylvanian epoch in Nova Scotia (approximately 312 to 304 million years ago). Paleothyris had sharp teeth and large eyes, meaning that it was a nocturnal hunter. It was about a foot long. It probably fed on insects and other smaller animals found on the floor of its forest home. Paleothyris was an early sauropsid, yet it still had some features that were more primitive, more labyrinthodont-like than reptile-like, especially its skull, which lacked fenestrae, holes found in the skulls of most modern reptiles and mammals. This book was created using print-on-demand technology. |
