Labidosaurus

Labidosaurus was an ancient reptile that lived in North America about 275 million years ago, during the Permian period.
It had a large head with a hooked upper jaw and a single row of conical teeth.
It was about 75 to 90 centimeters long and had a heavy, lizard-like body.
It belonged to the group Captorhinidae, which were the first reptiles to diversify and spread globally in the Paleozoic.
Labidosaurus may have been omnivorous, eating both plants and animals.

• Labidosaurus belongs to the family Captorhinidae, which includes some of the earliest reptiles that evolved from amphibians.

• Labidosaurus was heavily built, resembling a lizard with a large head.
  It measured about 75 centimetres (30 inches) long.

• Labidosaurus had a single row of conical teeth in its jaws, unlike many other captorhinids that had multiple rows of teeth.
  Its teeth were deeply implanted in the jaws, which limited tooth replacement.

• Labidosaurus had a distinctive hook-like snout, formed by the premaxillary bone that curved over the lower jaw.
  The function of this snout is unclear, but it may have been used for digging, grasping, or defense.

• Labidosaurus had small eye sockets that faced upward and sideways.
  It had a low and wide skull, with a sculptured surface.
  The back of the skull roof was slightly concave.

• Labidosaurus fossils have been found in Texas, in the red sandstone deposits of the lower Permian.

• Labidosaurus is closely related to the subfamily Moradisaurinae, which are large herbivorous captorhinids with multiple rows of teeth.
  Labidosaurus may have also eaten plants, but its diet was probably more omnivorous, including small animals such as insects and mollusks.

• Labidosaurus is one of the first captorhinids to be described, and the only recognized species is Labidosaurus hamatus.
  Some fossils that were previously assigned to Labidosaurus have been reassigned to other genera or to L. hamatus.

• Labidosaurus is the oldest known land vertebrate to show evidence of osteomyelitis, or a bone infection.
  A lower jaw of Labidosaurus had a broken tooth that exposed the pulp cavity to bacteria, causing inflammation and bone loss.
  This infection may have affected the animal's health and survival.

Labidosaurus was an extinct reptile that lived in the Early Permian period, about 290 to 273 million years ago.

It was found in North America, especially in Texas, where fossils of its skull and skeleton have been discovered.

Labidosaurus was an extinct reptile that lived in North America during the Permian period, about 290 to 273 million years ago.

It was a large and heavy animal, with a length of about 75 centimeters and a skull of about 20 centimeters.

It had a distinctive hook-shaped snout, formed by the premaxillary bone, that hung over the lower jaw.

It had a single row of sharp, cone-shaped teeth that were deeply implanted in the jaws.

It had small eye sockets that faced upward and sideways.

It had a low and wide skull, with a sculptured surface and a slightly concave rear edge.

It had 25 presacral vertebrae, two sacral vertebrae, and at least 33 caudal vertebrae.

It was probably an omnivorous animal, feeding on both plants and small animals.
