Late Cretaceous Period (Maastrichtian)- 69-66 Million Years Old Edmontosaurus Bone: 3.62 x 2.12 inches
(1 inch = 2.54 cm = 25.4 mm)
A recently prepared specimen, and well preserved Edmontosaurus (Hadrosaur) Bone with incredible bite marks all over the specimen! Are they from primitive mammals, raptors, I am unsure but to imagine who preyed on this creature sends the mind racing!
The Lance (Creek) Formation is a division of Late Cretaceous (dating to about 69 - 66 Ma) rocks in the western United States. Named after Lance Creek, Wyoming, the microvertebrate fossils and dinosaurs represent important components of the latest Mesozoic vertebrate faunas. The Lance Formation is Late Maastrichtian in age, and shares much fauna with the Hell Creek Formation of Montana and North Dakota, the Frenchman Formation of southwest Saskatchewan, and the lower part of the Scollard Formation of Alberta.
