Amphibians

1. Amphibians

   We know amphibians today as frogs, toads and salamanders, but they were far more diverse in prehistoric times, with some being apex predators the size of crocodiles. Amphibians differ from other vertebrates in that they lay their eggs in water, their young undergo metamorphosis before becoming adults, and they tend to have "slimy" skin which they breath through. In the commercial fossil market, one tends to find their fossils from German or China sources.
   
   Amphibians were the dominant land animals on Earth from the late Carboniferous to the early Permian, and that's where most of my collection come from.

2. MY BRANCHIOSAUR COLLECTION

   Branchiosaur: The rapacious branchiosaurs (meaning "gill lizard") are very early amphibians from early carbon to the early permian (roughly 290 - 300 million years ago). It was not a dinosaur. Like all amphibians, they had to live near the water since amphibian eggs have no shells and must be laid in the water (or in very damp areas) or they will dry out and die. Fossils of these salamander-sized amphibian have been found in Europe and Eastern North America. They were the closest relatives of the lissamphibians. Footprints and trackways of Branchiosaur Plainvillus are often found in a few locations in Eastern Massachusetts.
