reptile : any of a class (Reptilia) of cold-blooded, air-breathing, usually egg-laying vertebrates that include the alligators and crocodiles, lizards, snakes, turtles, and extinct related forms (such as dinosaurs and pterosaurs) and that have a body typically covered with scales or bony plates and a bony skeleton with a single occipital condyle, a distinct quadrate bone usually immovably articulated with the skull, and ribs attached to the sternum — Webster See also OneLook
Reptiles, as most commonly defined are the animals in the class Reptilia, a grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates (lizards and snakes) and rhynchocephalians (tuatara). In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. — Wikipedia
Herpetology is the branch of zoology concerned with the study of amphibians (including frogs, toads, salamanders, newts, and caecilians) and reptiles (including snakes, lizards, amphisbaenids, turtles, terrapins, tortoises, crocodilians, and the tuataras). Birds, which are cladistically included within Reptilia, are traditionally excluded here; the scientific study of birds is the subject of ornithology. Thus, the definition of herpetology can be more precisely stated as the study of ectothermic (cold-blooded) tetrapods. Under this definition “herps” (or sometimes “herptiles” or “herpetofauna”) exclude fish, but it is not uncommon for herpetological and ichthyological scientific societies to collaborate. — Wikipedia

- New modelling shows how interrupted flows in...on January 18, 2023 at 12:30 am
Flooding in Australia's Murray-Darling Basin is creating ideal breeding conditions for many native species that have evolved to take advantage of temporary flood conditions. Scientists have now developed virtual models of the Murray River to reveal a crucial link between natural flooding and the extinction risk of endangered southern bell frogs (Litoria raniformis; also known as growling grass frogs). Southern bell frogs are one of Australia's 100 Priority Threatened Species. This endangered […]
- Urban lizards share genomic markers not found in...on January 9, 2023 at 8:52 pm
Lizards living in different cities have parallel genomic markers when compared to neighboring forest lizards, according to a new study. The genetic variations linked to urbanization underlie physical differences in the urban lizards, including longer limbs and larger toe pads that show how these lizards have evolved to adapt to city environments.
- The other paleo diet: Rare discovery of dinosaur...on December 21, 2022 at 5:13 pm
Microraptor was an opportunistic predator, feeding on fish, birds, lizards -- and now small mammals. The discovery of a rare fossil reveals the creature was a generalist carnivore in the ancient ecosystem of dinosaurs.

- Development of the bony cap structure in digits...on January 26, 2023 at 3:14 pm
In the late 19th century, researchers discovered, in separate studies, that horses and humans have a small bone at the tip of their hoof and finger, respectively. Since then, research on the anatomical development of many animals—including horses, humans, and other species—has forged on, but little attention has since been given to this bony structure, which went unnamed for more than 100 years.
- Split-second of evolutionary cellular change...on January 23, 2023 at 10:47 pm
A newly-published hypothesis, led by a UCL researcher, suggests a momentary leap in a single species on a single day millions of years ago might ultimately have led to the arrival of mammals—and therefore humans.
- New pterosaur species with hundreds of tiny...on January 23, 2023 at 6:21 pm
An unusual new species of pterosaur has been identified, which had over 400 teeth that looked like the prongs of a nit comb.
