Ordovician (Red River Fm, Selkirk Mbr). Not in my collection, but where I work. :P The mottling is Thalassinoides.

Wow! Thats the ultimate hash plate! Such a wonderfull specimen! Congrats! Did you count how many different fossils (genera etc.) are on this plate?

 

I have another one, not as hashy as the above one, but it has something special to me, because it contains the four most abundant intertidal gastro species of the "Florianer Schichten" (Langhian, 15 Ma) within an area of 3x1.5 cm. From left to right:

Terebralia lignitarum; Granulolabium bicinctum; Vitta picta; Granulolabium plicatum; to the right is a G. bicinctum of normal size.

Oisnitz, St. Josef, Styria, Austria, wide of specimen is 7 cm, collected 2017.

Very nice! The younger gastropods certainly retain their features very well, which is something not so common in Paleozoic deposits from where I collect. 

 

Haven't counted up the fossils in the hash plate. I should say that this was found in the upper Verulam where it was a much stormier, high energy environment. The lower and mid Verulam sections are a bit calmer in areas, with alternating sections of crinoidal limestone and muddy shale intervals.

@Kane you have some stunning hash plates wow. Thanks for adding them this thread. 

 

@Tidgy's Dad Adam you’re the international man of hash plates . Norway and Australia. I really like the Australia plate. Cheers Bobby 

 

and thanks everyone for adding to this thread much appreciated.

Hash or lumachelle? There is not always that much difference:

Here are some accumulations of monotid bivalves from the upper Triassic Hallstatt limestone of the Northern Calcareous alps in Styria, Austria.

First specimen is from Frein, Mürztal. Collected 2015, field of view is 12 cm.

Second specimen is from Eisernes Törl, Schneealpe, Mürztal. Collected 2015, wide of specimen is 13 cm.

Third specimen: That´s a polished cross section through such a specimen from Eisernes Törl, Schneealpe, shell above shell.... Collected 2015, wide of specimen is 11 cm.

Only few people collect such stuff, the famous ammos from this formation are more popular, but they are not so easy to find...

Nice example of a worldwide index fossil. My best comes from Pine Pass in Northeastern B.C.  I don't know if this would qualify as a hash plate but it could be a # (number) plate as there are a number of them on it! (Accumulation plate I guess) We have them here on Vancouver Island too, and the ones I have would qualify more as hash plates and therefore not as showy.

I'm enjoying all this variety in hash/assemblage plates. In a way they are more interesting than isolated fossils - they are great as little snapshots of the seafloor (or swamp floor?) at some point in the distant past.

One of my favorite hash plates complete with Archimedes screws, a trilobite pygidium, and horn coral.

This is Permian age BTW. The trilobite belongs to one of the last orders of trilobites on Earth.

Now that is a really great monotid plate! I have yet to find such a large piece with such complete shells. A stunning specimen you are having here, thanks for sharing!

One of the funny things about this plates is, that they come in various colors. Black-grey-white and in various shades of pinkt to red. Sometimes they are multicolered (my second specimen).

Just saw your post today. Good timing. I just split this open last night to reveal the rock's innards. I need to pick away and expose things better. But the fresh split still is nice as is. Typical Galena, Ordovician fossils from Fillmore County, Minnesota

Thanks Franz. Yes, they aren't always the same color. The one I show is plain grey, but the lighting can fool you... (I need either a lightbulb that will give pure white light or a camera that won't exaggerate a light's tint!)

Hi FranzBernhard re my plates as Barton is comprised mainly of clay and sands these plates are uncommon and probably derived from shelly lenses found in A beds, especialy as they hold teeth.

Just curious if anyone can tell Me the difference between a "hash plate" and a "mortality plate"?

I thought Hash ( meaning mixed up) plates more just bits and pieces of creatures  that have fallen to the sea floor quite randomly  and a mortality plate was when the creatures have died at the same time and became fossilised. But I don’t the official definition.

I’ve always though hash was American and mortality UK/European!

I can't believe I almost missed this post. What I'm seeing is so fantastic. 

 

@Bobby Rico. You make the greatest posts!

 

For now I will contribute this array of sheet bryozoans.
