Amphibamus

By | September 9, 2016

Lush tropical forests and swamps covered the land in the Late Carboniferous Period. Giant insects buzzed around, and the newly evolved amphibians chased after them (see previous page). Some were as big as alligators, but tiny Amphibamus was the size of a newt. It had many of the features of modern frogs and salamanders and may have been their ancestor.

Amphibamus (AM-fee-bah-muss)

When: 300 million years ago (Late Carboniferous)

Fossil location: USA

Habitat: Swamps of N. America and western Europe

Length: 6 in (15 cm)

Diet: Probably insects

Amphibamus had large eyes for spotting prey. Perhaps it hunted by standing still and snatching insects that came close, as frogs do. Like most modern amphibians, it may have had to return to water to breed and lay eggs.

SKELETON

More than 350 million years old, this fossil of Amphibamus was found in Ohio. The wide head and large eye sockets are clearly visible.

SKIN BREATHER

Amphibamus fossils come from a site that was a river delta in the Carboniferous Period. Perhaps the animal lived in creeks or swamps near the river. Like most amphibians it might have been able to breathe through its moist skin, but it would have had to stay in damp places so its skin didn’t dry out.

Salamanders are related to frogs but have long, slender bodies. They live in damp places and can breathe through their moist skin. Some species lay their eggs in water, the eggs hatching out into tadpoles that breathe through gills. Others species breed entirely on land.
