Carnian ammonite from Epidaurus region Greece

[laiosx]

A speciment recently found in Argolis region of Greece . Upper Anisian - Carnian acording to the scripts but most probably Carnian

(lowermost Upper Triassic)

How big is it? Paranannites sp. is my best guess without information. Then it should be lower Triassic not Carnian. Any other co-found ammonoids to fix the age?

First pic looks like Acrochodiceras and last pic could be Procladiscites sp. But this is just my intention. All so far seen ammonoids point in my opinion to a Lower Triassic age. To be sure that it is Procladiscites and not (Upper Triassic) Cladiscites you need a visible sutureline. From form and shape alone you cannot divide them.

Adding information to this post, since it is totally pointless to open a new one. After all, we were together with Laios during most excursions there.

I will compile some species from this place, hoping to shed some light.

 

My main reference is this study

http://ikee.lib.auth.gr/record/76121/files/gri-2007-599.pdf

 

I completed this one today. Overall diameter is 3.5cm, thickness is 5.6mm and the inner diameter of the whorl (excluding the outer) is 2cm.

Leiophyllites aff n. sp. XXXIX, Pictures. 6 - 9 (page 423 of the pdf above)

 

This one measures 57mm in diameter and its thickness must be around 30mm. Cannot be precise since half side is still in the matrix.

My initial thought was:

Ptychites oppeli, affinity with XII, 13 page 396

Here are my first thoughts on this.

 

The next sample was gift from Laios.

As per your explanation, I would say

Procladiscites sp. I do not see the more complex form of Cladiscites sp.

23mm diameter with 3-4mm thickness. Right side of the picture is a zoomed section of the ammonite.

 

Maybe another Procladiscites sp. found by Laios.

Again, I see plain pattern on the sutureline.

 

Lastly, an ongoing project, long overdue.

Our yearly anniversary is soon, still not finished..

I cannot lean towards a family on this one.

the last one is Acrochordiceras sp. Age then is middle Anisian/Pelsonian. That would fit to the found Procladiscites and the Leiophyllites too.

Thank you Andreas for your valuable input!

Laios finished my Acrochordiceras. I have stopped around the stage of the 3rd picture, while it was found like the fourth.
