The American Museum of Natural History has this exhibit. I live so far away I probably won’t be able to go to this….but you might live closer!

This is the Introduction from their web site:
The world is full of stories about brave heroes, magical events and fantastic beings. For thousands of years, humans everywhere—sometimes inspired by living animals or even fossils—have brought mythic creatures to life in stories, songs and works of art. Today these creatures, from the powerful dragon to the soaring phoenix, continue to thrill, terrify, entertain and inspire us.
We seem to catch glimpses of these creatures all around us: hiding beneath the ocean waves, running silently through the forest and soaring among the clouds. Some symbolize danger. Others, we think, can bring us luck or joy. Together mythic creatures give shape to humankind’s greatest hopes, fears and most passionate dreams.
