as long as a human
A Lystrosaurus was a tetrapod that lived during the late Permian period. The Lystrosaurus is a distant relative of today's mammals.
Lystrosaurus is believed to have been diurnal, meaning it was active during the day. Fossil evidence suggests that it had eyes and other adaptations that were more suited for daylight activities.
it burrows into the ground with its barrelled chest
The labyrinthodont was 359-237 million years ago, lystrosaurus was 298.9-257.9 million years ago, and the duck billed dinosaur was 69 million years ago. That makes the labyrinthodont older.
Lystrosaurus went extinct at the end of triassic in the triassic-jurrasic extintion event at 200 million years ago during the break up of the supercontinent pangea with the alongside with the armoured archosaurs and some achosaurs and the dinosaurs take over the world in the early jurrasic.
lysttrosaurus was a medium sized reptile with two short tusks, it is in a class called the dyconadonts which became extinct at the end of the triassic period, and may be an adept swimmer. it is a herbivore, and it's fossils are found even in remote places like antartica.
Lystrosaurus lived during the Early Triassic period, approximately 250 million years ago, in a post-Permian environment characterized by a recovery from the Permian-Triassic extinction event. The climate was predominantly dry and arid, with some regions featuring seasonal rain, leading to a mix of open plains and sparse vegetation. Lystrosaurus thrived in this environment as a herbivorous synapsid, adapting to the harsh conditions with its burrowing lifestyle, which provided shelter from extreme temperatures and predators.
Jaguars are still alive.
it was found on two continents, including antarctica and south america.
Mesosaurus and Lystrosaurus provided evidence for the existence of Pangaea through their fossil distributions. Mesosaurus, a freshwater reptile, was found in both South America and Africa, suggesting these continents were once connected, as it could not have traversed the vast ocean separating them. Similarly, Lystrosaurus fossils were discovered in Antarctica, Africa, and India, indicating that these landmasses were once part of a larger supercontinent. The presence of these identical species across distant continents supports the theory of continental drift and the existence of Pangaea.
not for long
they were alive a long long time agoo lets just say that hahah
