Bony Fishes
the Teleostomi
While bony fish remains are relatively common, particularly in the Upper Gault, it is rare to find complete or articulated fossils. A successful method of collecting fish fossils is to bulk-sample the clay, dry and wash it, then sieve and sort through the residues with a hand-lens or microscope. This process will yield many tiny isolated teeth, vertebrae, scales, other bones and the otoliths (ear-bones) of fishes. Macro-fossils are usually limited to the occasional vertebrae and teeth. The teeth of Protosphyraena ferox Leidy are amongst the most common. Burrows attributed to Terebelloid worms are commonly lined with fish-scales and can be mistaken for complete fish fossils.

I am very grateful to Ms. Alison Longbottom of the Vertebrate Division of the Natural History Museum, London for providing identifications for the fish brain-case and albulid dentition.
