Diplocaulus went extinct approximately 250 to 260 million years ago. Diplocaulus lived in the Permian period lived in todays world North America. Their size can reach up to one meter in length. The skin had a slippery structure allowing for better locomotion in the water and on land.
The most distinctive feature that distinguishes it from other living things is its head structure in the shape of a boomerang. The reason why the head structure evolved in this way is unknown. The most thought on this subject is because to move faster in the water.
Studies have shown that the purpose of the weird head structure. Paleontologists suggest that the shape of the head acted as a hydrofoil allowing the animal to control the water flow over its head, concluding on Diplocaulus was better adapted for slower streams.
When Did The Diplocaulus Live
Diplocaulus lived Diplocaulus lived roughly 270 million years ago, from the late Carboniferous to the late Permian period.
Their diet was compromised mostly by small fish, insects, and amphibians that lived nearby the water.
Diplocaulids are considered to be completely aquatic. As amphibians live near bodies of water, the same it is with the Diplocaulus had to live near bodies of water for their reproduction as well. This was probably the reason for their extinction due to the mass extinction and drought during the end of the Permian period.
Diplocaulus Weight and Size
Diplocaulus could reach up to 3.3 ft (1 m) in length and weigh around 5-10 lb (2.3 – 4.5 kg).
