What to know about Paleontology

Researchers have identified a new species of giant Triassic amphibian-like creature, Arctobatrachus urdensis, from a fossil discovered in the Arctic. The specimen, the largest known plagiosaurid, was first spotted in 1948 and later recovered in 1984 before being analyzed by the State Museum of Natural History Stuttgart.

Why it matters

Unable to take it with them, they snapped some pictures, took some bones and left the fossil to be ravaged by the icy winds and rain.

Common ground

Little did they know it would be found again decades later and turn out to be the first of its kind and a giant among its peers.
