Cetaceans

There are a variety of cetacean fossils to be found in the Peace River though they are relatively uncommon. Typical remains are bones, such as vertebrae, ear bones and jaws, and isolated teeth. There are many more cetacean bones to be found but are often too broken or undiagnostic to classify as anything in particular. As with any bone it is important to check for bite mark as shark teeth often left deep grooves into cetacean bones that are still visible on the fossils today!

Porpoise

The most common cetacean to find in the Peace River are the variety of porpoise species in the Peace River. The one that I am familiar with is the genus Pomatodelphis. From porpoise one can find jaw bones, vertebrae, ear bones and teeth.

Jaws

Porpoise Jaws are long and slender, easily mistakable for a worn rib fragment. They are typically lacking any teeth or even fragments with very shallow indents where teeth used to be. They come in a range of preservation states but the main identifying factor to look for is shallow, round and regular indentations into a bone.

Section of porpoise jaw, notice the indents where teeth would have rested and the simple reverse. Always look at bone fragments just in case! Scale is 1cm
