Champsosaur and fish

Champsosaur and fish
Monjurosuchus & Lycoptera
Like many Liaoning fossils, this one captures the remnants of several animals that died simultaneously, perhaps killed by a volcanic event. The champsosaur, a superficially crocodile-like reptile, is about a foot long. Fish are the most common backboned animals in the fossil beds, and the most prevalent are herring-like Lycoptera. Fossil hunters have discovered thousands of specimens in a single layer of sedimentary rock. Aquatic animals and plants, in general, often became spectacular fossils, as fine-grained sediments were likely to drift to the bottoms of lakes and ponds.
