Al Dente Posted May 24, 2015 Share Posted May 24, 2015 These are actually rotula from the Aristotle's lanterns of the Oligocene urchin Gagaria mossomi. About 4 mm. each. 2 Link to comment Share on other sites More sharing options...
Auspex Posted May 24, 2015 Share Posted May 24, 2015 Neat!

Diceros Posted May 24, 2015 Share Posted May 24, 2015 Eric - Are these the structures which hold the sea urchin teeth in the Aristotle's lantern (same as the pyramid plates?), or are they the teeth themselves? If the latter, which is the working end? You're the Master of Marine Obscurata, Eric! Link to comment Share on other sites More sharing options...

Five rotula are arranged in a radial pattern on top of the lantern with the esophagus in the middle. I'm guessing they serve to support the hemipyramids.

JohnJ Posted May 25, 2015 Share Posted May 25, 2015 Great assemblage, Eric. It took me a while to figure out what these were in the lower Cretaceous strata I hunt.

Doctor Mud Posted May 25, 2015 Share Posted May 25, 2015 The resemblance to Gummy Bears is uncanny. I showed my wife without telling what they were: "they look like Gummy Bears - very stale ones though" :-) Thanks. The Fossil Forum is always a source of surprises and wonder. I'll know what these are if I come across Gummy Bears in my neck of the woods. Link to comment Share on other sites More sharing options...
