How can you describe Cynognathus?
Cynognathus was approximately as large as a modern wolf and, like the wolf, was an active predator. The body of Cynognathus was not massively constructed. The tail was short, and the limbs were tucked well under and close to the body, providing the potential for rapid and efficient locomotion.
What are Cynognathus fossils?
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). It is found as fossils only in South Africa and South America.
What time period did Cynognathus live?
247.2 million years ago – 228 million years ago (Anisian – Carnian)Cynognathus / Lived
Did Cynognathus lay eggs?
Paleontologists believe Cynognathus sported a thick coat of hair and may have given birth to live young (rather than laying eggs, like most reptiles); we know for a fact that it possessed a very mammal-like diaphragm, which enabled it to breathe more efficiently.
Why did the 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.

Are we cynodonts?
Mammals are cynodonts, as are their extinct ancestors and close relatives, having evolved from advanced probainognathian cynodonts during the Late Triassic.
Do cynodonts lay eggs?
Characteristics. Cynodonts have nearly all the characteristics of mammals. Their teeth were fully differentiated, the braincase bulged at the back of the head, and many of them walked in an upright manner unlike reptiles. Cynodonts still laid eggs, as all Mesozoic proto-mammals probably did.
What type of animal is Cynognathus?
Cynognathus is an extinct genus of large-bodied cynodontian therapsids that lived in the Middle Triassic. It is known from a single species, Cynognathus crateronotus. Cynognathus was a 1.2-metre (3 ft 11 in) long predator closely related to mammals and had a southern hemispheric distribution.
How big is a Cynognathus crateronotus?
Life reconstruction of Cynognathus crateronotus. 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, 30 centimetres (1 ft) in length, with wide jaws and sharp teeth.
How big was the Cynognathus Wolf?
However, it probably didn’t hunt live modern wolves and probably lived a fairly solitary life. Cynognathus was approximately 3 feet long and weighed around 15 pounds. That made it about half the length of an adult male wolf and weighed a little bit more than an average house cat.
Did Cynognathus lay eggs or give birth?
Paleontologists believe Cynognathus sported a thick coat of hair and may have given birth to live young (rather than laying eggs, like most reptiles); we know for a fact that it possessed a very mammal-like diaphragm, which enabled it to breathe more efficiently.
