|Sayre native Gerry Corbin with fossils he recently donated|
One of the donations is a fossilized fish embedded in limestone. These herring-like fish flourished during Eocene time, about 50 million years ago, in three vast freshwater lakes. They are unusually well preserved in laminated limestone precipitated from calcium-rich waters. The limestone is interbedded with many thin layers of volcanic ash and mudstone.
The second fossil is much more rare and is of a well-preserved example of an Inadunate Cladid crinoid known as Cyathocrinites (Family Cyathocrinitidae). Its serially branching arms formed a most effective basket for filtering out the minute particles upon which it fed. This one has an attached stem, making it a more desirable example than many seen. Crinoids are a group of sea creatures that are still alive today. The majority of crinoids attach themselves to the sea-floor, and have a long, flexible 'stem', with a crown of tentacles at the top. Although crinoids look like plants (which is why they are also known as sea-lilies), they are animals that feed on tiny creatures (plankton). It lived around 350 million years ago in the geological time period known as the Lower Mississippian Osagean Stage.
