Pseudosphaerodon antiquus jaw fragment collected from the Eocene Bracklesham Beds of Lee on Solent in Hampshire. Pseudosphaerodon is an extinct genus of ray finned fish which lived during Lower to Mid Eocene times. Without a highly trained eye and vast knowledge of fossil fish anatomy it would be difficult to discern this piece as a jaw fragment. Regardless of this, it is a rare specimen thus is of value to serious collectors. It measures approximately 6 mm in length and is supplied in a small glass cylinder with an information label. The Bracklesham beds in which this jaw fragment was found were laid down on a shallow marine shelf, they have yielded fossils of over 160 different species of fish and the beds continue to be productive today despite having been pillaged by collectors for over 100 years.
