The walls of Moscow Metro preserved full ecosystems of fossils, coral reefs and its inhabitants, lots of sponges and various shellfishes and echinoderms. In the Metro there are fossilized shells of various cephalopods - ammonites, nautilus, belemnites, shells of marine gastropods and bivalves, fragments of skeletons of echinoderms - stalks of crinoids and sea urchin needles. Often there are shells of marine animals brachiopods, which are sometimes confused with bivalves. Sometimes well-preserved corals and sponges are in the walls.

As for the dinosaurs along with any other fossil vertebrates, you will not find them in the walls.
