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 — Merriam-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

Science

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

A team of researchers recreated a life-size oviraptor nest to investigate how these bird-like dinosaurs incubated their eggs millions of years ago. By combining physical experiments with heat transfer simulations, they discovered that oviraptors likely relied on both their own body heat and warmth from the sun.

A giant black coral estimated to be 300–400 years old has been discovered deep in Fiordland, New Zealand, astonishing researchers with its enormous size—about 4 meters tall and 4.5 meters wide. Scientists say it may be one of the largest black corals ever recorded in New Zealand waters and an important stronghold for the slow-growing species.

A newly identified crocodile species nicknamed “Lucy’s hunter” prowled Ethiopia’s rivers when Lucy’s species walked the Earth more than 3 million years ago. The giant predator was likely the most dangerous animal in the ecosystem and may have regularly hunted early human relatives.

When trying to attract and recognize potential mates, animals are known to rely on various signals, traits and behaviors. In the case of birds, these signals can typically include a wide range of sounds—such as trills, whistles, chirps or melodious notes defined as "songs"—as well as the color and movement of their feathers.
