[Xenocidaris]

A very nice topic!

I'm adding some of my corals, starting with Sphenotrochus intermedius. The first two pics are from a specimen from Belgium, the third photo shows a sample of the same species from the now closed locality of Miste, The Netherlands (Miocene) (purchased).

Then a big, almost 7 inch, specimen of Favosites from the Devonian of the Eifel, Germany. Continued on the next post.

[Xenocidaris]

Then Heliolites and a closeup of it, also from the Eifel.

To end another Favosites, an Ordovician one from Germany.

Sincerely,

Bram

Here's my only local coral - at least I think it is only one species with some variation - Platycyathus sp. Upper Santonian Haslam Fm, Vancouver Island. Often found growing on Inoceramus shells, but at my local site it's found on its own. Hard to find ones with the tops exposed because the septa tend to hold the matrix while the bottoms are smoother so they will break free, but you can see the edge of the top in the bottom right pic.

Forgot the scale but these are about 1cm diam.. can be larger; I have a partial one about 2cm.

BTW top 2 are the same specimen and bottom two are the same.

EDIT: These might actually be a kind of Cidaroid echinoid spine. If so, I'll remove this and put elsewhere; stay tuned!

Excellent specimens everyone with some of them being marvels of the nature!!!

Here is one big late miocene scleractinian of my coral collection found in middle Crete island, Greece and a close up of it

Here are several pics of my corals. Mostly obtained from NC reworked surf and Puerto Rico beachs... Enjoy. Jeff/Tarheel

These are four of my un-identified corals. Would appreciate it if anyone could help to ID 'em.

The yellow-brown coral from the top left comes from Africa, and has several small tube-like growths around it. I bought it from the Hong Kong seller, gaofudev. The other three fossils were picked up from the beaches of Singapore, Thailand and Bintan.

[Sinopaleus]

below is a giant horn coral from the devonian of guangdong province, china. species is currently unidentified.

[dudeman]

Here is my favorite one that I found;

Honey comb coral?

The rest are all ones I have found but do not have any ID's

[dudeman]

More corals I found....

[squalicorax]

Nice dudeman

your last piece is a really nice halysite coral that I bet would dissolve real nice in some acid.

[glacialerratic]

Here's my best Halysites, with matrix removed using muriatic acid.

Ratio of acid used is given, but I think next time I'd cut that in half and do a longer soak.

[nearpass]

I posted this in the ID part of the forum a few weeks ago. Large clump of solid 'organ pipe' coral of some kind, no idea of the scientific name. Middle Devonian from NY.

[JohnnyMorales]

Here's a decent piece of coral I found near Belton Lake in Bell County Texas

Wonderful, Thomas

Some very nice corals displayed, as well...

Here is one scleractinian coral I have found in my birth place (late miocene Crete island, Greece).

EDIT: These might actually be a kind of Cidaroid echinoid spine.

As I had said it in the other post speaking about these fossils (I didn't find again Ssuntok's post...), I made pics of Philippine Psychocidaris ohshimai to show the attachment of its different spines. Here are !

This one shows the Psychocidaris ohshimai species

This one shows the attachment point of the upper spines

And the last one shows the attachment point of the lower spines (they are useful not to sink into the marine sediment)

As you can see, the part which comes to fasten on the body of the sea urchin is always finer than the spine. It is this part which I can't see on your fossils.

There is the other thing which can help to make the difference if your fossils are in calcite : the break of calcite sea urchin spine is never parallel or perpendicular of the spine, we always observe the same angle of break. I forgot to make a photo of a broken spine to show you. You go to have to wait a little !

Eric, enjoy !

Here are some Ordovician colonial coral from Washington Co. Kentucky from the Drakes Formation. I wasn’t sure how the cab would turn out when I started but there seems to be a lot of Quartz replacement in it.

[howard_l]

This is a Rugose Ordovician coral from the Bull Fork of Flemingburg KY

Here is a Silurian colonial coral from Crestwood, KY . and a Rugose coral from the Silurian Brassfield of Estill Co. KY
