Fossils have been found in the Karoo, the Puesto Viejo Formation, Fremouw Formation, in South Africa/Lesotho, Argentina and Antarctica. Cynognathus lived between the Anisian and the Ladinian (Middle Triassic). This genus forms a Cynognathus Assemblage Zone in the Beaufort Group of the Karoo Supergroup.

Was Cynognathus a warm-blooded?
Technically classified as a "cynodont," or dog-toothed, therapsid, Cynognathus was a fast, fierce predator, much like a smaller, sleeker version of a modern wolf. ... Most startlingly, evidence points to Cynognathus having a warm-blooded, "mammalian" metabolism, quite unlike most of the cold-blooded reptiles of its day.
How long did Cynognathus live on Earth?
Take a look at some unusual living and extinct mammals!
Cynognathus was an early relative of mammals. It lived about 235-250 million years ago. Cat-sized Repenomamus was the largest known mammal from the Mesozoic "Age of Dinosaurs."
On which continents did Cynognathus live?
Cynognathus was as large as a modern wolf and lived during the early to mid Triassic period (250 to 240 million years ago). It is found as fossils only in South Africa and South America.
Can the Cynognathus swim?
Cynognathus and Lystrosaurus were land reptiles and were unable to swim. Grooves and rock deposits left by ancient glaciers are found today on different continents very close to the equator. This would indicate that the glaciers either formed in the middle of the ocean and/or covered most of the Earth.
How did the Cynognathus live?
This therapsid lived on open plains during the early to middle Triassic period, roughly 230-245 million years ago. It was probably warm-blooded and may have given birth to live young. Diet and Teeth: Cynognathus was a fast-moving carnivore (a meat-eater).
Is Cynognathus still alive today?
Modern day representation of the Cynognathus. The now extinct Cynognathus, which translates to “dog jaw”, was a mammal- like reptile. Roaming the terrains during the Triassic period (250 to 240 million years ago), the Cynognathus was as large as a modern wolf.
Is the Cynognathus still alive?
Cynognathus, genus of extinct advanced therapsids (mammals and their relatives) found as fossils in Lower Triassic deposits (251 million to 245.9 million years ago) in South Africa and South America. The teeth were regionally specialized on the jaw into different forms, as in mammals. ...
Is a Cynognathus a dinosaur?
Cynognathus was a cynodont (a mammal-like reptile, not a dinosaur) that was the size of a wolf. This therapsid lived on open plains during the early to middle Triassic period, roughly 230-245 million years ago. It was probably warm-blooded and may have given birth to live young.
What type of fossil is Glossopteris?
Glossopteris, genus of fossilized woody plants known from rocks that have been dated to the Permian and Triassic periods (roughly 300 to 200 million years ago), deposited on the southern supercontinent of Gondwana. Glossopteris occurred in a variety of growth forms.
What did Cynognathus look like?
Appearance and Lifestyle. Based on fossils, Cynognathus was about one meter long, with a stocky build. Its legs were positioned beneath its body as it walked, which suggests that it had a mammalian-like gait.
What is the meaning of Cynognathus?
Definition of Cynognathus
: a genus of large carnivorous therapsid reptiles (suborder Theriodontia) that greatly resembled mammals in form, were presumably near the direct ancestral line of the true mammals, and are known chiefly from remains found in the Karroo formation of the Triassic.
What was Alfred Wegener's theory?
In the early 20th century, Wegener published a paper explaining his theory that the continental landmasses were “drifting” across the Earth, sometimes plowing through oceans and into each other. He called this movement continental drift.
Where was mosasaurus found?
In Badlands National Park, mosasaur fossils have been found in the Pierre Shale, a rock unit laid down in the Western Interior Seaway roughly 75-69 million years ago.
What does the location of Glossopteris fossils give evidence for?
Glossopteris fossils were critical in recognizing former connections between the various fragments of Gondwana: South America, Africa, India, Australia, New Zealand, and Antarctica.
Where was the Lystrosaurus found?
Lystrosaurus was part of the Dicynodontia (an extinct group of mammal-like reptiles), part of the larger synapsid clade of vertebrates which includes living mammals. Its fossils have been discovered in Africa, India, and Antarctica.
