although amphibians were the first vertebrates to live on land, they were _____. boundaries the transition from water to land required animals to surmount several ________.(the most critical were desiccation, reproduction, the effects of gravity, using lungs for oxygen rather than gills. Giant salamander-like labyrinthodont amphibian from the Triassic period which lived in lakes in the Sydney basin. A complete fossil skeleton was found in the St Peters brick pits in and is now in the Natural History Museum, London.
Answer is labyrinthodont. About million years ago, labyrinthodonts (maze-toothed), a group of extinct were evolved from lobed-finned fish in the Devonian period. They were dominant animals in the rift valley was present at that time between Antarctica and Australia. -Reptiles and amphibians. Reptiles and mammals.
