In July 2018, I visited the American Museum of Natural History in New York City, USA. While there I came across the Hall of Biodiversity and the variety of spiny invertebrate sea creatures on display.
Around the Louisville area we find the fossils of spiny creatures (brachiopods and snails) and while not common finds they peak the interest as what they fully looked like.
See these past posts of some of the fossils found: Productella spinulicosta (Devonian), Echinoconchus alternatus (Mississippian), Platyceras dumosum (Devonian), Productella spinulicosta (Devonian), Productella? (Mississippian), and Platyceras dumosum (Devonian).
Images above show spiny gastropods on display at museum. They were not identified by name.
Modern spiny sea creatures seen that museum were Cat's Tongue Oyster (Spondylus linguaefelis) found in Hawaii, USA.
American Thorny Oyster (Spondlylus americanus) found in southeastern United States down to Brazil.
Regal Thorny Oyster (Spondylus regius) found in western Pacific Ocean.
Did not identify these next two.
