, you´re right, sorry

Ahhhh, I just noticed that too, so ................................

 

from the Paleocene Aquia Formation of Maryland

 

an undescribed myliobatoid (according to Elasmo.com)

Miocene? Anyone?

[siteseer]

Here's the positive and negative of a pea crab, Pinnixa galliheri.  This is actually the first specimen I ever found.  It had fallen and rolled on the ground, already split as you see here.  That's easy fossil collecting!  It's usually not that easy.  You have to split some shale to get one and you have to be lucky to get a split like this one especially with that nice color.

Nice bird bone.  It's great when you can find that much of a long bone.  I have quite a few fragments.

There can be a lot of variation with those teeth.  It might not be an undescribed form.

That is correct. It should probably read an undetermined myliobatoid.

I've already shown a good number of finds from this site on the Hook Peninsula in Wexford County, Ireland, but here's yet another one. A Caninia cornucopiae coral attached to a Unispirifer sp. brachiopod. It has a ø of 2.5cm. and was pried out of the Ballsteen Limestone Formation, Carboniferous Mississippian Tournasian stage.

When I was looking through the newest added photos I thought your first image was a bivalve! What a cool trilobite!

@Jeffrey P  totally jealous of your crinoid calyx. I have a disarticulated Graffhamicrinus calyx from near there, but not one all together! It's lovely!

That’s one heck of a prep job. Very nice

A 2.5cm. long Lingula sp. brachiopod with a teeny tiny ammonite on the matrix which I never did get around to identifying. From the Late Triassic Norian Hallstätter Kalk on the Feuerkogel in Salzburgerland, Austria and found on an excursion in 2014.
