Adelobasileus

Adelobasileus is an extinct animal that lived about 225 million years ago in the Late Triassic period.

It is considered to be a mammaliamorph, which means it was closely related to the ancestors of mammals.

It is known only from a partial skull found in Texas, USA.

Adelobasileus had some features that were similar to mammals, such as a complex inner ear with a coiled cochlea, which is used for hearing.

It also had a large brain and a short snout.

However, it also had some features that were different from mammals, such as a single opening behind the eye socket, which is typical of reptiles and other synapsids.

Adelobasileus was probably a small, insect-eating animal, about the size of a mouse.

It may have been nocturnal and used its sensitive hearing to find prey.

It was one of the earliest mammaliamorphs, and it predates other groups of mammaliaforms, such as Morganucodonta and Docodonta, by 10 million years.

It is thought to be a transitional form between more primitive cynodonts and more advanced mammaliaforms.

Adelobasileus was named by Spencer Lucas and Adrian Hunt in 1990, after Alfred Crompton, a paleontologist who studied early mammals.

Adelobasileus is a rare and important fossil that helps us understand how mammals evolved from their reptilian ancestors.
