3.9" Rare Odontocephalus - Exceptional Specimen
The specimens that were collected back in the 80's were crudely prepared using acid etching. This destroyed the shell which was then "recreated" using shoe polish. So, nearly all of the specimens of Odontocephalus in existence don't have actually shell.
This specimen come from a small lot that was discovered unprepared wrapped in newspaper in the basement of a collector several years ago. These specimens were then prepared using the latest preparation techniques. This is one of only a handful of Odontocephalus from Pennsylvania that have actual shell preserved.
