When did dicynodonts go extinct?
about 210 million years ago
This animal should not be living alongside our Cretaceous dinosaurs. All of the text books say that dicynodonts died out about 210 million years ago in the late Triassic.
When did Placerias go extinct?
Placerias (meaning ‘broad body’) is an extinct genus of dicynodonts that lived during the late Carnian age of the Triassic Period (221–216 million years ago)….Placerias.

When did Kannemeyeria go extinct?
Kannemeyeria are extinct therapsid (mammal-like reptiles) that lived approximately 250 million to 230 million years ago, during the Early to Middle Triassic Period. Data from the fossils describe Kannemeyeria as herbivores (plant eaters).
Are dicynodonts extinct?
Dicynodontia is an extinct clade of anomodont therapsids. Dicynodonts were herbivorous animals with a pair of tusks, hence their name, which means ‘two dog tooth’….Dicynodont.
| Dicynodont Temporal range: | |
|---|---|
| Phylum: | Chordata |
| Clade: | Synapsida |
| Clade: | Therapsida |
| Suborder: | †Anomodontia |
How did Therapsids survive the Permian extinction?
Summary: Paleontologists have demonstrated that ancient mammal relatives known as therapsids were suited to the drastic climate change by having shorter life expectancies and would have had a better chance of success by breeding at younger ages than their predecessors.
What happened to bring an end to the Permian period?
The Permian (along with the Paleozoic) ended with the Permian–Triassic extinction event, the largest mass extinction in Earth’s history, in which nearly 81\% of marine species and 70\% of terrestrial species died out, associated with the eruption of the Siberian Traps.
Why did Placerias go extinct?
They aren’t sure just why this animal went extinct. Some paleontologists have theorized that better developed dinosaurs came along and drove them into extinction. However, it also could have just as easily been climate change that doomed these large herbivores.
What kind of Therapsid was Placerias?
Placerias was a dicynodont (a group of mammal-like reptiles) that lived during the late Carnian age of the Triassic Period (221-210 million years ago). It was a member of the family Kannemeyeridae, the last known representative of the group at this time: the dicynodonts went extinct shortly afterwards.
What type of organism was Kannemeyeria?
Kannemeyeria was a herbivorous dicynodont dinosaur the lived in South Africa, Argentina, India and China during the Triassic Period.
What environment did Kannemeyeria live in?
Kannemeyeria were land-dwellers. They traveled throughout plains and swamps, staying in warm, dry climates close to the equator. Interestingly, fossils of Kannemeyeria have currently been found in rock layers across North America, South America, Africa, and Asia.
