Carnivore·Late Triassic·Southwestern United States (New Mexico)·Bipedal
Coelophysis is a small, slender, bipedal carnivore that lived during the late Triassic period, approximately 215 to 201.4 million years ago. It is one of the earliest known dinosaur genera, with extensive fossil discoveries primarily from the southwestern United States. Its hollow bone structure inspired its name, meaning "hollow form."

About Coelophysis
Coelophysis: An Early Triassic Predator
Coelophysis is a genus of small, slender theropod dinosaurs that roamed the Earth during the late Triassic period, approximately 215 to 201.4 million years ago. It is recognized as one of the earliest known dinosaur genera, with its fossils primarily discovered in the southwestern United States, particularly in New Mexico.
Discovery and Naming
The genus was first described by Edward Drinker Cope in 1889, who named it from Greek words meaning "hollow form," referencing the distinctive hollow structure of its bones. The type species, C. bauri, was named in honor of German paleontologist Georg Baur. The genus has a complex taxonomic history, with several other names, such as Longosaurus and Rioarribasaurus, later determined to be synonymous with Coelophysis.
Paleobiology and Fossils
Coelophysis was a bipedal carnivore, typically growing up to 3 meters (9.8 feet) in length. Its lightweight, hollow bones suggest it was an agile predator. The fossil record for Coelophysis is remarkably extensive, with hundreds of individuals found in a single concentration at the famous Ghost Ranch quarry in New Mexico. This abundance of specimens, representing various ages and sizes, has made Coelophysis one of the most well-understood early dinosaurs, providing significant insights into dinosaur evolution and paleontology.

Frequently Asked Questions
When did Coelophysis live?
Coelophysis lived during the late Triassic period, approximately 215 to 201.4 million years ago. This timeframe spans from the middle Norian to the Rhaetian age.
What does the name Coelophysis mean?
The name Coelophysis comes from the Ancient Greek words 'koilos' (hollow) and 'fysis' (form). This name refers to the characteristic hollow structure of its bones, a feature common among theropod dinosaurs.
Where were Coelophysis fossils found?
The most significant discoveries of Coelophysis fossils have been made in the southwestern United States, particularly in New Mexico. Material representing similar animals has also been found in various locations worldwide from Late Triassic and Early Jurassic formations.
How large was Coelophysis?
Coelophysis was a relatively small dinosaur, growing up to approximately 3 meters (9.8 feet) in length. It had a slender build, indicative of its agile nature.
What did Coelophysis eat?
Coelophysis was a carnivore, meaning it primarily ate meat. Its diet likely consisted of small animals available during the late Triassic period.
What is special about the Coelophysis fossil record?
Coelophysis is notable for being one of the earliest known dinosaur genera and having an exceptionally rich fossil record. Hundreds of skeletons have been found, providing extensive data on its anatomy and life.
Related Dinosaur species
Camposaurus
Camposaurus is a small, carnivorous theropod dinosaur from the Late Triassic period of North America, specifically the Norian stage. It is widely considered to be one of the oldest known neotheropod dinosaurs, with its fossil remains discovered in Arizona.
Chindesaurus
Chindesaurus is an extinct genus of basal saurischian dinosaur that lived in the southwestern United States during the Late Triassic period. Known primarily from a partial skeleton discovered in Petrified Forest National Park, Arizona, this bipedal carnivore was roughly the size of a wolf. Its exact classification has been a subject of debate among paleontologists, with various studies suggesting it was a herrerasaurid, a basal saurischian, or a theropod closely related to Tawa.
Daemonosaurus
Daemonosaurus is an extinct genus of dinosaur from the Late Triassic period, known from a single skull and neck fossil discovered in New Mexico. It possessed an unusual short skull with large, fang-like teeth, and its exact placement within dinosaur phylogeny is debated, possibly representing a basal theropod or basal saurischian.
