Styxosaurus & Ichthyodectes
North America, Niobrara Formation
In the sunny waters of the shallow Western Interior Seaway, ichthyodectid fish scatter before an elasmosaur. Styxosaurus reached 12 metres in length, half of which was neck and probably ambushed its prey using its long neck to pick off small fish.
Baculites, a form of straight shelled ammonite hang in the water column. With a variety of shell morphologies they are excellent indicator fossils and can help palaeontologists date sediments precisely.
