A few weeks ago I had a chance to chat with Paul Taylor in the Paleontology department of the Natural History Museum. I was chatting with him about a curious specimen that has, over the years, gained a little bit of notoriety in the museum’s collection. You see, it was a mystery.
What you’re looking at is a slide of Dinocochlea ingens. On the left, you’ve got the original 1922 paper which detailed the 1921 finding; in the middle, an image from a newspaper of the day (which I think would make a brilliant T-shirt!) depicting the scale of the odd find; and on the far right, you can see a scan of the only photo that records the original “in ground” condition of the specimen.
1. It is a fossil of a FREAKISHLY big snail!
2. It is a coprolite, a.k.a the remnant of a giant turd (most likely from an Iguanodon).
3. It is a concretion fossil formed from the indents left underground by a spiraling path of a very small burrowing most likely worm-like organism.
