Sphenodiscus lenticularis, Fox Hills Formation, South Dakota Late Cretaceous (~ 70 mya)  This specimen displays the extraordinarily intricate suture patterns that are characteristic of this species. Also evident is part of the beautifully iridescent nacreous layer. A laterally flattened ammonite, this animal is thought to have been a relatively fast swimmer.
