How big were Cynognathus?
Cynognathus was a heavily built animal, and measured around 1.2 metres (3 ft 11 in) in snout-to-vent body length. It had a particularly large head, up to 40 centimetres (1 ft) in length, with wide jaws and sharp teeth.
Which is true about Cynognathus?
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. ... Cynognathus was approximately as large as a modern wolf and, like the wolf, was an active predator.
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.
Why did Cynognathus go extinct?
As the climate became more arid, the plant species upon which the prey of Cynognathus fed died out, and a (food) chain of events followed. Cynognathus became extinct sometime in the middle Triassic, about 215 million years ago.
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?
This suggests that South America and Africa were joined during the Early Permian. Cynognathus is an extinct mammal-like reptile. The name literally means 'dog jaw'. Cynognathus was as large as a modern wolf and lived during the early to mid Triassic period (250 to 240 million years ago).
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.
What did a Cynognathus eat?
Diet and Teeth: Cynognathus was a fast-moving carnivore (a meat-eater). It had powerful jaws and dog-like teeth, including sharp incisors, long canines, and shearing cheek teeth. This predator hunted herbivores like Kannemeyeria (another early therapsid) in packs.
On which continents did Cynognathus live?
Roaming the terrains during the Triassic period (250 to 240 million years ago), the Cynognathus was as large as a modern wolf. Its fossils are found only in South Africa and South America.
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 did Glossopteris look like?
Glossopteris occurred in a variety of growth forms. Its most common fossil is that of a tongue-shaped leaf with prominent midrib and reticulate venation. Glossopteris leaves are commonly found in thick mats, and thus some authorities speculate that the plants were deciduous.
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.
When did the Lystrosaurus become extinct?
Lystrosaurus, extinct genus of about seven species of medium-sized heavily built animals that lived from the middle of the Permian Period (298.9 million to 251.9 million years ago) until early in the Triassic Period (251.9 million to 201.3 million years ago).
How did the Mesosaurus move?
It probably propelled itself through the water with its long hind legs and flexible tail. Its body was also flexible and could easily move sideways, but it had heavily thickened ribs, which would have prevented it from twisting its body. Mesosaurus had a small skull with long jaws.
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.
