  Moscow is one of the few cities with paleontological monuments of world significance on its territory. One of them is the Gorodnya River with its tributaries, on the banks of which outcrops of the Quaternary and older Cretaceous periods are located. Fossils of the bivalve mollusk Inoceramus kleinii and tubular passages of burrowing animals, described in 2017 as a new ichnospecies Skolithos gorodnensis, were discovered in the Coniacian deposits near the stream bed of the Bolshaya Glinka River. Ichnogenera Diplocraterion, Planolites, Skolithos and possibly Ophiomorpha were found in the Albian deposits. Paleolithic flint tools were discovered in the Quaternary deposits of the Bolshaya Glinka stream bed.
  
  In 1878, paleontologist Hermann Trautschold discovered the left flipper of an ichthyosaur near the village of Mnevniki, which later became part of Moscow. In 2014, the animal was named Undorosaurus trautscholdi, after its discoverer. Trautschold determined the age of the sediments from which the specimen was taken to be Kimmeridgian, but, according to more recent studies, they were formed in the Tithonian age of the Jurassic period.
  
  Albian foraminifera and ammonites also known from the Moscow deposits.
  
  Fossils of various organisms are on display in Moscow museums, including the Orlov Museum of Paleontology and Vernadsky State Geological Museum.
