Brachiopod Fossils. The most common seashells at the beach today are bivalves: clams, oysters, scallops, and mussels. However, from the Cambrian to the Permian (542 to 252 million years ago), another group of organisms called brachiopods dominated the world's oceans. Over 12,000 fossil species of these hinge-valved organisms have been described ... Wide-hinged spiriferid brachiopods (below left) have been likened to birds. For example, in China, the common name of such forms translates as 'stone swallows'. There they are boiled in water with various herbs to produce medicinal potions and powders.This is a very large spiriferid brachiopod fossil. It looks like a large, more robust, version of M. audaculus. It is very rounded, and the hinge line is not straight, but is slightly concave. It's called spinocyrtia because of fine spines (almost like tiny hairs) that cover the brachiopod. These spines are only preserved on exceptional specimens.

The spiriferid brachiopod Spiriferina abichi and the discinid brachiopod cf. Orbiculoidea sp. also occur in and adjacent to the Liard biostromes.
