Fossil Snake Egg - Bouxwiller, France

This is a very unusual fossil, it is an Eocene aged fossil snake egg from Bouxwiller, France. These were laid on the bank of a lake about 50 million years ago. The rock formation was exposed in a now abandoned quarry and over 44 vertebrate species have been described from the location 30 years ago. These eggs are typically attributed to Ophidenovum by collectors, but it's probably nearly impossible to know for sure.
