This extraordinary fossil specimen captures a dramatic moment from the Upper Cretaceous period 70 million years ago: a Leidyosuchus crocodilian tooth embedded in the fossilized shell of a Trionyx softshell turtle. This remarkable predator-prey interaction fossil offers not only scientific intrigue but exceptional natural artistry. The fractured reddish-brown turtle shell reveals the bite mark of a long-extinct crocodilian, providing a rare glimpse into prehistoric behavior frozen in time.

An exceptional acquisition for advanced fossil collectors, natural history enthusiasts, or museums seeking a unique vertebrate interaction specimen. From The Lance Formation in Weston County, Wyoming, its scientific relevance, visual impact, and rarity make this a standout display and investment-grade fossil.

The embedded Leidyosuchus tooth measures 0.68″L x 0.25″H.
