(DSM# 10676) Extinct genus - Mortoniceras is commonly known from sediments of the Western Interior Seaway. The seaway was a wide swath of sea that roughly cut North America in half north to south during the Cretaceous and early Paleocene periods.
(unnumbered) Extinct genus - Many ammonite specimens found in the Tombigbee sand do not show well preserved suture marks. This makes it more difficult to identify the fossil to species level.
(DSM DH13) Extinct family of large fish sometimes called the "saber-toothed herring". Enchodus were common in Late Cretaceous seas and survived the K-Pg extinction event. They went extinct in the Eocene.
(DSM#10765) These Hadrosaur specimens were found in marine sediments which suggests the animal died and floated into the ocean before sinking and being preserved.
