sues, h.d., and reisz, r.r., 1998, origins and early evolution of herbivory in tetrapods: trends in ecology
Nina [5.8K]

Origins and early evolution of herbivory in tetrapod's About 300 million years ago, in the Late Carboniferous, the first herbivorous tetrapod's evolved. By the Late Permian, continental ecosystems of `modern' character had been formed, with a massive standing crop of herbivores sustaining relatively few predators. In order to process high-fiber plant material, it is necessary to make anatomical changes to the jaw, digestive system, and dentition as well as to acquire microbial endosymbionts that can create the enzymes required for fermentative digestion of cellulose, the main component of plant cell walls. Recent tetrapod phylogenetic studies show that several lineages separately developed endosymbiotic cellulitis throughout the late Paleozoic.

What is tetrapod's?

Animals classified as Sarcopterygii include tetrapod's. Tetrapod's, which include hawks, frogs, and turtles, are land-dwelling creatures. Along with such, there are marine creatures including sea lions, whales, sea snakes, seals, dolphins, and sea turtles.
