Some Fossils Found That Day: Crinoids and Corals
And now, ladies and gentlemen, the pictures of crinoids found that day. There
were lots of crinoid stems found.
I saw someone had found a nice Cincinnaticrinus pentagonus calyx
(below).
Here's a really interesting and somewhat mysterious mass of crinoid arms. This
may be a large number of calxes bunched together, or one crinoid of a type I
cannot identify. Jack? What's your analysis?
Corals
There were also lots and lots of Horn Coral found. This one is a Grewingkia.
I think the coral in the picture below is Streptelasma.
This is a complete coral head of the colonial tabulate coral, Tetradium.
It will be pretty nice once it is cleaned.
This is a broken Tetradium coral (below)
