Si tu as des coraux de l'éocène du bassin parisien des photos seraient les bienvenues pour voir ce dont il s'agit et éventuellement les identifier

un Baroniseris accolé

Hi Elasmo!

Very nice specimen! I think this is Cyathoseris, but not sure.)

[elasmo]

Thanks Cyathoseris it's old name of Baroniseris

Hi.

Very interesting corals, very good conservation.

I would attach a pair of images.

Details columnilla and septa similar to those presented in this post as belonging to Aren (Spain) and classified as Trochocyathus sinuosus.

Greetings to the participants in the post.

Another coral with associated a shell :

These associations are always very interesting specimens

Congratulations

Rhizangia brauni (Michelin 1846) associated with Turritella gastropods, fragments of bivalves and among themselves

The lack of suitable substrate forces them to develop this way

Holà !

Sería la zona SBZ11 ?

Podriamos hacer un subjeto sobre el Ilerdiensie !

[oyo]

Hola.

No, sería SBZ 7.

Sería interesante.

Es claro que estos materiales poco tienen que ver con los de Paris bassin.

Un saludo.

Hi.

No, it would be SBZ 7.

It would be interesting,
It is obvious that this type of material has little to do with that from the Paris Bassin.

Greetings.

Si muy diferentes. Pero la Turitella parece simular a las que tenemos.

Claro 7 ! El limite Paleoceno - Eoceno es SBZ4/5. Mas tarde hablamos...

[oyo]

SBZ 11 sería Cuisiense.

SBZ4 Thanetiense y SBZ 5 es Ilerdiense inf.. Es el límite Paleoceno-Eoceno, así es.

Hablamos cuando quieras.

[oyo]

Estos Rhizangia brauni estaban antes y después de ese límite Paleoceno-Eoceno.

Ejemplares procedentes de SBZ4 Thanetiense sup. Formación Esplugafreda. LLeida. Spain

La asociación esta vez es con Tympanotonos (Eotympanotonos) hypermeces Cossman 1898, dentro de lo poco que yo se de gasterópodos

Resulta complicado restringir los corales a un estrato concreto, en la mayor parte de las ocasiones.

Lo digo por el posible post ¿"Ilerdiense" ,"Eoceno Inf.", "Paleogeno"?

These Rhizangia brauni were before and after the Paleocene-Eocene boundary.

SBZ4 specimens from Thanetian sup. Esplugafreda form. Lleida. Spain

This time the association is with Tympanotonos (Eotympanotonos) hypermeces Cossman 1898, in the little I know of gasteropods.

It is difficult to restrict the corals to a particular stratum, in most of the time.

I say this because of a possible post ¿"Ilerdian", "Eocene Inf.", "Paleogene"?

[elasmo]

Very nice

[Next50MY]

This species is well know to be from brakish environment. Have you details on the gastropods you show here ?

[oyo]

Very nice

Se trata de una asociación poco habitual.

It´s an unusual asociation.

This species is well know to be from brakish environment. Have you details on the gastropods you show here ?

Y muy interesante, precisamente por eso.

¿Me pides detalles morfológícos del gasterópodo, fotografías?

Sobre el gasterópodo ya he comentado que no tengo seguridad. No tengo conocimientos sobre ellos.

And very interesting, because of it.

You ask me for morphological details of the gasteropod , photographs?

On the gastropod I mentioned that I have no security. I have no knowledge about them.

Mi intención participando en el post era aportar datos para la clasificación de estos ejemplares.

Greetings to the participants in the post.

Aportando estas tomas.

Providing these images.

[oyo]

En mi opinión ambos ejemplares son lo mismo.

El clasificado como Trochocyathus terqueni no es otra cosa que un ejemplar patológico de la misma especie que el primero.

In my opinion both specimens are the same.

The classified as Trochocyathus terqueni is nothing but a pathological specimen of the same species as the first.

Por otra parte, la adscripción genérica (Trochocyathus) creo que no es correcta.

Se trata de una denominación muy antigua de este tipo de ejemplares, hoy por hoy revisada.

Moreover, the generic assignment (Trochocyathus) I think it is not correct.

This is a very old name for this specimens, today reviewed.

[Next50MY]

Just a surprise to find the associated bioclasts. Probably the Tympanotonus was not in place, there might be turbiditic deposits including coastal mollusca.

[oyo]

El gasterópodo yacía semienterrado.

Los corales ocuparon la parte expuesta.

Gastropod lays half buried.

Corals occupied the exposed part.

Remarques. - Les echantillons figures par Brongniart et par Michelin representent deux

especes differentes. Tous les auteurs apres Michelin n'ont pas tenu compte de cette difference.

Il en resulte une grande confusion dans la diagnose de cette espece.

Opinión de Nicole Vadois-Mieja 1964.

Quizás tenga más peso que la mía.

Conviene puntualizar que desde 1964 ha llovido bastante.

Perhaps more weight than mine.

It should point out that since 1964 it has rained much.
