Page 5: More Fossil Finds


By far, the most abundant fossil on this site was the brachiopod. Here, for example, is a typical mix of fossils found. Almost all of them are brachiopods.

Close examination of the articulate brachiopods, Rafinesquina and Strophomena, reveal that the brachs were encrusted with inarticulate brachiopods, such as the Petrocrania scabiosa shown below.

The most common brachiopod are the articulates. And among the articulate brachiopods on this site, the most abundant is Lepidocyclus, with varying species.  Shown, above, is an example with both sides. It belongs to a group of brachiopods called Rhynchonelid's, which includes another common brachiopod found on this site, but not pictured, Rhynchotrema dentatum.

Much smaller than the Lepidocyclus, but just as common on this site, is the brachiopod Zygospira. These brach's have the same "haring bone" pattern as the Lepidocyclus, but belongs to a group of related brachiopods called Atrypids.
