Turkey or Dinosaur for Thanksgiving?

After eating a Thanksgiving meal (above image wish bone of dinner's main dish), I came across an article in the Washington Post about how turkeys are related to dinosaurs. About 250 million years ago (mya), the group Archosauria tree split between Pseudosuchia (ancestors of the crocodile) and Dinosauria (eoraptor),then at 240 mya the tree split again to Saurischia, Theropoda (225 mya), Tetanurae (190 mya), Maniraptora (180 mya) to today's modern birds (Avialae).

Watch the video below, as it will explain how modern birds with limbs with 3 digits, wishbones and hollow bones relate today's birds with the dinosaurs of the past.

Modern Day Spiny Sea Creatures

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.
