While reading a book about Mesozoic reptiles by Dougal Dixon, I was dumbstruck to read to Jurassic deposits in western Cuba have yielded pterosaur fossils, including the rhamphorhynchids Cacibupteryx and Nesodactylus. Years later, however, I also found out that ground sloths, ammonites, flightless owls, rodents, plesiosaurs, thalattosuchians, and ichthyosaurs have also been found in Mesozoic and Pleistocene deposits in Cuba. Did you ask any paleontology and fossil fans when they first learned that Cuba has yielded fossil tetrapods from marine and Pleistocene deposits?
