A short walk in the Hauterivien of Switzerland.

[blueyoung]

Hello everyone,

For this first report I take you to visit a small site in the Hauterivien. A few kilometers from the village of Hauterive which gave it its name.
(Sorry for the quality of the photos I was with my nephew aged 14. And the rain made us go home prematurely)

In this region the Hauterivien is composed in its upper part of a yellow limestone called "Pierre jaune de Neuchâtel". (It has served a lot in the construction.) Below is layers of marl called "Marnes d'Hauterive". These are the layers we are going to explore.
Some views of the career:

 

In this photo, we can see the succession of layers:

Snow and water did their job of clearing during the winter:

Much of the site is still subject to winter landslides. We will avoid setting foot there. The wall is still unstable.

A sample of the finds of the day:

Lamellaerynchia, Musclina and Plicarostrum make up most of the brachiopod fauna of the quarry.

I still managed to get my hands on a much less common Belothyris. And on this copy that I have not yet identified. I have not found anything comparable on this site yet.

 

Some sea urchins that can be found on the site:

The inevitable and very common Toxaster retusus:

Holaster Intermedius:

Pseudodiadema rotulare:

That's all for this ride.

Very interesting and informative. Thank you for posting! 

I love those brachiopods! 

Hello, and a very warm welcome to TFF from Morocco! 

I enjoyed the ride. 

[FranzBernhard]

Thanks for the virtual trip - very nice area, very nice fossils!

Nice finds! Thanks for sharing!

[ynot]

Welcome to TFF!

Looks like a fun place to hunt.

You found some nice stuff too.

Thanks for sharing.

[Ludwigia]

Thanks for the glimpse into the Hauterive from the area which gave it its name. Very interesting!

[Kane]

That area looks so full of promise! Thanks for the virtual tour, and some very nice finds from an area I don't get to see (virtually) much.  

[jpc]

Very nice.  Thanks for the tour.  

[izak_]

Very nice! I love the brachs 

[Peat Burns]

Nice finds. Thanks for showing the brachiopods.

[Jeffrey P]

Very nice brachiopods and echinoids. What formation and age is that? Congratulations and thanks for sharing.

[Pilobolus]

Thanks for sharing!  Your shots are actually quite nice! The shot of the sediments is fun for this pattern-seeking vertebrate. I reproduce it below to ask what the thingy is to which I've pointed:

[Monica]

Beautiful finds and beautiful scenery - thanks for sharing!!!

[Bobby Rico]

Great post, great finds and beautiful photos thank you. 

[MeargleSchmeargl]

Stuff's looking for fine!

To me that looks like another brach like the one above it, from a different angle.

 

Looks like a fun place to collect!

[jpc]

That is what I saw too... another brach.  

[Miocene_Mason]

Awesom! Thanks for sharing

And another one in red

Hello,
Excellent question! This allowed me to see that the age of these layers was redefined in 2016.
It starts at the late Valanginian (Zone at Radiatus) to finish at the early Hauterivian (Zone at Loryi) for the "Marnes d'Hauterive.
Then from the early Hauterivian (End of the Zone to Loryi) to the late hauterivian (base of the Zone to Sayni) for the "Yellow Stone of Neuchâtel.

Previously they were considered fully Hauterivian.

They are part of the formation of the "Formation of Grand Essert"

All this in the lower Cretaceous.

 

Thank you all for your encouragements.

 

[Jeffrey P]

Thank you. I was thinking Jurassic or Cretaceous.

@blueyoung, maybe a lamp shell - order Terebratulida?

Maybe I'm wrong but radiatus zone is lower hauterivian and not valaginian

That's what I always thought too. The new dating would be in this publication. Unfortunately considering the price I have other priorities for the moment.
