Missourian Posted February 13, 2012 Share Posted February 13, 2012 I am guessing this would qualify as a Hash-Plate. It is a "Gob" of Belemnite from the Black Hills of South Dakota. I did not personally find it but I like it a lot. FYI, we found many similar belemnites from the Redwater Shale member of the Sundance Formation near Sturgis, SD. Yours are probably from the same unit. Context is critical. Link to comment Share on other sites More sharing options...

newdog65 Posted February 18, 2012 Share Posted February 18, 2012 Here are a couple of hash plates from the Cranbrook, BC area. one is a small plate that I have to clean up a bit but has a number of mixed parts and complete labiostria westropi. Other is a large plate of mostly olenellus cephalons, but a few wanneria mixed in for good measure. Chris N 1 Link to comment Share on other sites More sharing options...

masonboro37 Posted June 30, 2012 Share Posted June 30, 2012 (edited) Hash plate with a mix of bryozoa and ocean floor goodies. It is really this yellow color. Found after the quarry blasted. Location: Rocky Point, NC Martin Marietta Quarry Assuming Eocene. Edited June 30, 2012 by masonboro37 Process of identification "mistakes create wisdom".

squalicorax Posted September 29, 2012 Share Posted September 29, 2012 Nice baby brachs on there Missourian. Are those casts left of larger brachs that have weathered?

Missourian Posted September 29, 2012 Share Posted September 29, 2012 (edited) Nice baby brachs on there Missourian. Are those casts left of larger brachs that have weathered? The clasts are enigmatic. They appear to be concretions, but yet they are contained within the dense hash. Perhaps they formed in the adjacent shale, and were pushed into the still-soft limestone sediment during compaction. They could also be burrowing, but I wouldn't expect the concentric structure.

andreas Posted October 1, 2012 Share Posted October 1, 2012 Nice! Are those from that day together ? Hi Roger! No they aren't. These are from another Tuvalian location. This was the material in the boxes, you have seen downstairs in front of the door to my prep room. I hope you are well!

squalicorax Posted October 1, 2012 Share Posted October 1, 2012 Incredible plates paleostone. That Silurian one is killer. Really nice brachiopods on that one. Oh and of course the Jurassic boundstone is quite nice. Do you know how early Triassic that 3rd plate is?

Thank you for the compliments ... Does anyone recognize these briachiopods ? I have another specimen of a different color : Muschelkalk with brachiopods from third photo, belongs to Middle Triassic, about 230-240 million years ago. Greatings ...

garyc Posted October 2, 2012 Share Posted October 2, 2012 Cool thread. Do any of you coat your plates with something to make the fossils stand out. Floor wax, maybe? Picked this up in central Texas. Link to comment Share on other sites More sharing options...
Missourian Posted March 29, 2013 Share Posted March 29, 2013 Middle Creek Limestone, Pennsylvanian Jackson County, Missouri The Derbyia brachiopod in the lower center is 16 mm wide. This slab has by far the most diverse assemblage I've ever seen in the Middle Creek. The large number of mollusks clustered together is unusual. Normally, there is one or two, if any.

taj Posted March 29, 2013 Share Posted March 29, 2013 (edited) Not a plate , but a ball. From a very little site which had its time of fame ( samples are in Lamarck collection..). Took me a lot of time to realize it was sitting practically in my garden . From the aalenian : Mix of Leioceras, gastropodes, trigonias.... Interesting for me is the high number of ammonitellas in this block( see details). I will find the time someday to prepp it....

Missourian Posted June 9, 2013 Share Posted June 9, 2013 I figured I'd resurrect an old thread with a modest offering.... Hash block Westerville Limestone, Pennsylvanian Kansas City metro This limestone is a grainstone, which is made up of fossil debris that had been swept clean of finer particles. It formed on a shoal in very shallow water. The fossil grains are wave-worn and include algae, bryozoans, mollusks, ostracods and trilobites, among other things. Beautiful specimens of larger fossils -- most notably cephalopods and trilobites -- can be found in a few places, but I didn't spot any in the wall. The voids between the grains later filled with sparry calcite. This makes the rock quite resistant to breaking and weathering. That is why they used it in the patio wall on the backside of my workplace, where I snapped this photo. The little red things are spider mites. Those things seem to be everywhere.
