Tiny Stuff From Hungry Hollow

[Kane]

The day began with a morning hunt at my honey hole at "riprap hill," and I was pretty much skunked. I think, after four years, I've picked the place over. There is virtually nothing left for me to split, and given a mild winter, nothing new has weathered out. But I at least was graced by the sight of the living in the form of this majestic animal:

It was then a trip to Hungry Hollow. We focused on the south pit as the river level was running dangerously fast and high after some heavy rainfall in the last while. Nothing exciting beyond the usual stuff, so I focused on picking up tiny bits as I enjoy doing that even if I have so much of the stuff already. Here is the sampler pack: a diverse array of crinoid bits, a few coral, two Microcyclus ("button coral"), some brachs, a large number of Bactrites nautiloids (some with fairly good preservation), and down along the right edge seven Tornoceras in descending size (they don't get very big in the Arkona Fm).

As the "tornos" are so small, I decided to put my scope on them to bring out their detail (the first two are a gastro and a brach, but the rest are the tiny tornos). The grid I use (above and below) is 5mm x 5mm (0.19685 inches x 0.19685 inches). Magnification at 75x.

Great finds. Do you find crowns of the crinoid Arthroacantha in the Hungry Hollow?

Thanks! Nothing fabulous, but good practice with patience. In terms of that crinoid, I do believe Arthroacantha carpenteri can be found, but it is a slog to go through the Arkona mudshale overburden, and lots of precautions are required for removal and storage (not letting it dry out too quickly, and never getting it wet!). Since much of the Arkona is blank, it takes a lot of patience and sweat to find the crinoid lenses.

This is actually a pelecypod (Paracyclas lirata).

Thanks for the save... I knew that, but typed in haste!

Thanks.  Those "ribbed" columnals are reminiscent of the columnals of A. carpenteri, but I don't know how many other taxa have similar columnals or whether the connection can be made.  In the Silica Formation, the most common crowns I found were A. carpenteri, and those similar columnals were everywhere   But, again, I know that matching loose columnals to a crinoid taxa can be difficult or impossible.

Nice haul. That's a lot of fossils and the nautiloids I think have the most interesting shapes.
