Broom , 1915 |
The Brachyopidae are an extinct group of aquatic, medium-sized terrestrial vertebrates from the Temnospondyli group . The taxon was introduced by Robert Broom in 1915 .
They lived mainly in the Triassic , but have also been found in the Central Jura of China and Mongolia. The late forms likely survived in regions that were geographically isolated or had cool climates so that they were not colonized by crocodiles .
Outwardly, they resembled today's giant salamanders . Her head was broad and flat, and her large eyes were set far forward. They had large fangs in their upper jaw and were probably fish-eaters. The animals spent most of their lives in the water. The legs were relatively small and were probably only used to move from one body of water to another.
