I found that coral in the Kimmeridgian of la pointe du Chay, Charentes-Maritime. I have a documentation that shows some corals of that area and the one that looks like more is the Pseudocoenia hexaphyllia, what do you think it is ?

The hole in which it is is about 4 cm on 3 cm.

Nice scleractinian coral. ...like flowers in the spring :)
Also we have a few genera in Romania, Dobrogea. Besides Pseudocoenia (including P. hexaphyllia) and others there is one named Proaplophyllia sexradiata (RONIEWICZ, 1966).

Pseudocoenia is a problematic genus due to an unlucky designation of a type specimen of the type species. By now, it is a synonym of Stylina, Alloiteaucoenia, or Heliocoenia, according to the various sources. - Your samples looks to me a mould of a Stylina. Having a picture with scale included, the species can be surely assigned.

Above i indicated the size of the hole. As soon as i can i'll give the size of the "flowers".

The size of the "flower" and between them can be of 4 millimeters. For those who only know the inches : 1 inch = 2,5 centimeters and 1 centimeter = 10 millimeters.

The diameter is surely not 4 mm, there is with certainty a variation. I also do not know how you did measure the diameter since it is a mould.

If the diameterof the inner corallite is about 4 mm, it could be Stylina tumularis (Michelin, 1841) that occurs from the Oxfordian into the Aptian.

It's the size of some of the largest "flowers" and the largest space between two of them. The diameter and space i was able to measure is surely about 4 mm.. I measured it with a tape measure used for stitching  because i needed Something flexible enough. I only could measure somes near the border because my fingers are too big to measure the ones in the center of the mould.

Visually, the largests i measured looked to be the same size than the largests in the center.

I guess that the variation we see can be due to the stage of growth of each animal.

Thanks @doushantuo and @abyssunder for the documents.

I tried to do better measures of the coralites, but it's hard to do the more precisely possible, and the result is not about 4 mm but is more near of 3 mm. I'll try to post some pics after work.

I'm sorry, but when this is holidays there is a lot of people on internet and my connexion is sometimes impossible or very slow. Here is a pic with a scale.IMG_0240.thumb.JPG.b059613fe08eeeb14288e8e148015b00.JPG

Veo que la Rioja es cerca de Pamplona, Huesca y Burgos. No es tan lejos de donde vivo en el sud de Francia, cerca del Pais Vasco.

Ahí estoy, sí. Somos casi vecinos.

A ver si le gustan sus nuevas fotos al Sr. HansTheLoser.
