Context: Paleontology in Delaware refers to paleontological research occurring within or conducted by people from the U.S. state of Delaware.  There are no local rocks of Precambrian, Paleozoic, Triassic, or Jurassic age, so Delaware's fossil record does not begin until the Cretaceous period.  As the Early Cretaceous gave way to the Late Cretaceous, Delaware was being gradually submerged by the sea.  Local marine life included cephalopods like "Belemnitella americana", and marine reptiles.  The dwindling local terrestrial environments were home to a variety of plants, dinosaurs, and pterosaurs. Along with New Jersey, Delaware is one of the best sources of Late Cretaceous dinosaur fossils in the eastern United States.  Delaware was still mostly covered by sea water through the Cenozoic era.  Local marine life included manatees, porpoises, seals, and whales. Delaware was worked over by glaciers during the Ice Age.  The Cretaceous belemnite "Belemnitella americana" is the Delaware state fossil.
