Back to the ditch

[Ludwigia]

I mentioned here about a week ago that I had discovered a promising new exposure in that Kimmeridgian ditch at the side of the road which I thought I'd pretty well exhausted over the last few years. I also said that I would probably go back again soon and true to my own word, I did. This time I took the car. I spent about 2 hours there and made some more good finds. They are all out of a concretionary horizon in the hypselocylum zone of the Lochen Formation sponge facies. It looks like there could very well be more to be found, so I guess I'll be going back there again before the snow sets in.

 

Ataxioceras (Parataxioceras) hypselocylum, the ammonite which gives the zone its name.

 

 

Parataxioceras sp.

 

Streblites tenuilobatus together with a partial Ataxioceras sp.

 

Taramelliceras sp.

 

Taramelliceras sp., Lingulaticeras sp. and a Laevaptychus obliquus, part of the jaw aparatus from an ammonite.

Very nicely done, Roger. It's a treat when an older, picked-over site still has a bit more to give -- or at least some new pockets you haven't gone through. And even when the snows do come, they don't seem to stick around for too long in your neck of the woods.

Yes, I suppose you're right compared to what you have to deal with over there every year.

Very nice finds, love the contrast of color with the ammonites and pale matrix. As Kane says its great when an old site gives a bit more!

I like the Ataxioceras (Parataxioceras) hypselocylum. Is the red color mineral staining? It gives some of the suture lines a very neat look.

Great finds Roger

 

what is the size of the Ataxioceras hypselocylum?

Thanks Archie.

The red is iron, the green glauconite.

12cm. in diameter. The second one is 13cm.

Nice ammonites. We have the same fauna in southeast France. Are you sure for the Ataxioceras sp with the Streblites? It looks like Orthosphinctes.

I think the Laevaptychus belongs to Aspidoceras acanthicum. In France we find them together

More nice finds and much easy by car than BMX .

I don't think that it's Orthosphinctes. The only species I have in the literature is Ardescia shairieri, whose form is quite different. All other species come in earlier zones. You are correct about the aptychus.

The suture patterns and colors on the Ataxioceras are marvelous to behold. The ammonite jaw piece is impressive as well. Congratulations Roger on another successful hunt.

Ditto to what the others said.

(Really liking the jaw piece!)
