Wooster’s Fossil of the Week: Encrusting craniid brachiopods (Upper Ordovician of southeastern Indiana)
The two irregular patches above are brachiopods known as Petrocrania scabiosa encrusting the ventral valve of yet another brachiopod (Rafinesquina). That species name “scabiosa” is evocative if not a little unpleasant — it is also the root of the English … Continue reading →

Wooster’s Fossils of the Week: Hyoliths (Middle Ordovician of Estonia)
The fossils above are about as simple as fossils can be. They are internal molds (sediment-fills) of conical shells that were made of the carbonate mineral aragonite. The aragonite shells dissolved away after death and burial, leaving the cemented se… Continue reading
