What habitat did the Cynognathus live in?
What habitat did the Cynognathus live in?
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.
When were Cynognathus fossils found?
Cynognathus was a mammal-like reptile which lived approximately 245 million to 230 million years ago during the Middle Triassic Period. It was first discovered in 1895 by British paleontologist Harry Seeley and was given its name the same year.
What environment did the Lystrosaurus live in?
(Refusing to subscribe to the second theory, some paleontologists believe that Lystrosaurus actually thrived in the hot, arid, oxygen-starved environments that prevailed during the first few million years of the Triassic period.)
When did Cynognathus live?
247.2 million years ago – 228 million years ago (Anisian – Carnian)Cynognathus / Lived
Where are Lystrosaurus fossils 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.
Where were Mesosaurus fossils found?
Mesosaurus fossils have been found in South America and Africa.
When was Cynognathus extinct?
about 215 million years ago
Cynognathus became extinct sometime in the middle Triassic, about 215 million years ago.
How big is a Cynognathus?
Cynognathus was a heavily built animal, and measured around 1 metre (3.3 ft) in body length. It had a particularly large head, 30 centimeters (1.0 ft) in length, with wide jaws and sharp teeth.
What two places are the fossils of Cynognathus located?
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 does the word Cynognathus mean?
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.
Why the fossils of Lystrosaurus Mesosaurus and Cynognathus are found in places that are oceans apart?
Lystrosaurus fossils are only found in Antarctica, India, and South Africa. Similar to the land dwelling Cynognathus, the Lystrosaurus would have not had the swimming capability to traverse any ocean.
What type of habitat did Mesosaurus live in?
freshwater lakes and ponds
Mesosaurus lived in freshwater lakes and ponds. Elongated and slim, it measured about 1 metre (3.3 feet) long. The skull and tail were both long and narrow, and the animal probably undulated through the water as it fed on small crustaceans and other prey with its jaws, which were full of long, thin, pointed teeth.
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 continents were Lystrosaurus fossils found?
Which fossil type was found in South America Antarctica Africa and Australia?
The Glossopteris fossil is found in Australia, Antarctica, India, South Africa, and South America—all the southern continents. Now, the Glossopteris seed is known to be large and bulky and therefore could not have drifted or flown across the oceans to a separate continent.
How long is a Cynognathus?
3.9 ft.Cynognathus / Length
What two continents are the fossils of Mesosaurus and Cynognathus found?
º Look for all of the pieces with the fossil remains of Cynognathus and put them together first (South America and Africa).
Where Mesosaurus fossils are found?
Mesosaurus, (genus Mesosaurus), early aquatic relative of reptiles, found as fossils from the Early Permian Period (299 million to 271 million years ago) in South Africa and South America.
What fossils have been found in Antarctica?
Animal fossils Dinosaurs lived in Antarctica and are well known from the northern tip of the Antarctic Peninsula, although few have been described formally. They include ankylosaurs (the armoured dinosaurs), mosasaurs and plesiosaurs (both marine reptilian groups).
Why is the fossils of Lystrosaurus Mesosaurus and Cynognathus are found in places that are oceans apart?
Cynognathus and Lystrosaurus were reptiles that lived on land. Both of these animals were unable to swim at all. Their fossils have been found across South America, Africa, India, and Antarctica. Wegener thought that all of these organisms must have lived side by side.
What is the first fossil ever found in Antarctica?
The first fossil found was the Plesiosaurs, (marine reptile), it was found in Seymour Island in 1982.
Are there fossils under the ice in Antarctica?
Share selection to: In around 1833 the first specimens of fossilised wood from Antarctica were reported by surgeon, naturalist and artist James Eights. We now know that fossils are, in fact, abundant in Antarctica, and the most common are of wood and leaves.
