Some brachs from Pyrenean Toarcian

[Quer]

Hi all,

 

Some weeks ago, I found a site pretty rich in brachipods from the Late Pliensbachian/Early Toarcian in my area (Pedraforca Zone, SE Pyrennes)

 

So, I made a parenthesis in my Upper Cretaceous usual issues, for a change, and I have been picking & preparing them last weeks.

 

This site is very well studied in this paper (in French), and in fossilworks. I probably i found all the species mentioned from the site:

 

Telothyris pyrenaica

 

 

 

 

Telothyris jauberti

 

 

 

Quadratirhynchia vasconcellosi

 

 

 

 

Soaresirhynchia sp. Soaresirhynchia (Alméras, 1994) (former Stolmorhynchia) is a genus of  little brachiopods first described by Alméras in a study about Portugueses Toarcian specimens, but are common in all the Iberian-Pyrenean Toarcian basin, from Portugal to South France.

Unfortunately, they show great morphology diversity, and I must confess the I am not be able to distinguish one specie from another (S.bouchardi, S.flamandi, S.rustica). Maybe @ricardo could help.

 

These are some examples:

 

 

 

 

Homoeorhynchia batalleri

 

 

 

 

And finally, the only Liospireferina falloti I found, though in poor condition:

Yum yum! 

Those are lovely brachiopods.

Nice prepping too.

Hello,

 

Very nice specimens. Unfortunately I´m not an expert and  I can´t help you with a scientific answer . Our Toarcian has some of those species. See attached paper please.

 

Greetings,

Nice pieces!

[Quer]

Thanks !

 

From same site, in an older bed (Spinatum zone -189.6 to 183.0 y.o.-, Pliensbachian)

 

Aulacothyris resupinata, easy to ID because of its "buxom" brachial valve

 

 

 

 

Lobothyris cf. punctata (not easy to differentiate from Telothyris jouberti)

 

 

 

Other fauna from the site: Belemnites (Not ID, likely Passaloteuthis or Acrocoelites)

 

 

 

 

A tiny ammonite, too eroded to ID, and some bigger pieces (sutures are clearly visible)

 

 

 

 

 

And a pair of Pseudopecten sp.

The Aulacothyris is particularly nice.
