I’ve mistaken a few clams for Brachiopods, but there is a difference. Brachiopods tend to be a mirror image from left to right, whereas Clams are mirrored from top to bottom if you look at them straight on. There is still a lot I have to learn about Brachiopods in general.
Brachiopods Through Time
Brachiopod diversity was generally high throughout the Carboniferous. However, after the period changed to the Permian, diversity sharply declined and never recovered to levels sustained from 485 until 299 million years ago.
Today, there are about 100 living genera. However, there have been about 5,000 discovered in the fossil record.
Brachiopods from Parks Township
Brachiopod Specimens from the Catalog
Several brachiopods are in the general collection, and a handful have been entered into the catalog. The following specimens have been entered.
