While amphibians continued to feed on fish and later insects, reptiles began exploring two new food types, other tetrapods (carnivory), and later, plants (herbivory). Carnivory was a natural transition from insectivory for medium and large tetrapods, requiring minimal adaptation (in contrast, a complex set of adaptations was necessary for ...
When complete, the list below will include all food plants native to the Americas (genera marked with a dagger † are endemic), regardless of when or where they were first used as a food source. For a list of food plants and other crops which were only introduced to Old World cultures as a result of the Columbian Exchange touched off by the ...
The amphiuma's predatory behaviors and food selection are very calculated and variable depending on abundance of food. In addition to eating frogs, snakes, fish, crustaceans, insects, and other amphiuma, amphiuma have been found to eat annelids, vegetables, arachnids, mollusca, and larvae. [12] Amphiuma seem to have a preference for eating ...
Amphibamus is a genus of amphibamid temnospondyl amphibians from the Carboniferous (middle Pennsylvanian) of North America. [1] [2] [3] This animal is considered to have been close to the ancestry of modern amphibians. Its length was about 20 centimetres (7.9 in). [4]

D. magnicornis was the first species known from more than vertebrae, and it allowed Cope and other paleontologists to realize the nature of Diplocaulus as a bizarre long-horned "batrachian" (amphibian). [11] Much of modern knowledge on the genus is based on this species, as it outnumbers any other Diplocaulus remains by hundreds of specimens.
Aquatic plants require special adaptations for prolonged inundation in water, and for floating at the water surface. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common.
