Very nice ammonites and very good preparation, congratulations. Are they Aegocrioceras of Hautervian?.

I attach a Pthychoceras sp. of the Barremian de La Alcoraya (Alicante).

Here is a Christmas find from Texas on my hunt with SnakeKeeper.

Not specimen quality, but still kind of interesting... at least for me. B)

Hey Patarradio looks nice this one ;)

Si vols un "LP" d'aquests, jo t'ajudo a aconseguir-lo, però hauràs de baixar al sud dels Països, i allí no hi ha crancs ballant la jota :D .

Greetings all.

Let me take you on a tour of a single piece of rock, about 7 cm across, containing four specimens of Polyptychoceras with several inoceramids and a conifer. It's from the Late Cretaceous of Japan.

Side 1 shows the conifer sprig, about 9 cm around the curve.

Moving in a bit closer ... look for a tiny bright near-spherical object to the right of the conifer sprig with a darker straight section extending downwards.

Here it is up close .. a 3 mm hatchling Polyptychoceras with a fine ammonitella.

Zooming on the ammonitella ..

Now let's flip the rock around to look at side 2 ..

Above the Inoceramus is a 26 mm juvenile orthocone stage in the growth of the Polyptychoceras.

Here it is ..

Now let's move around to side 3 ..

post-2199-12520768840946_thumb.jpg

To the left is a more mature juvenile, 34 mm long, which has completed its first U bend. The 28 mm straight section above the Inoceramus shows the siphuncle very clearly.

and finally a more mature individual, 10.5 cm long, which has gone through four U bends (one of which is very early and not visible in the photo)..

It's a very nice piece. I really enjoy seeing different species in the same matrix. Welcome to the Forum.

The whole piece has amazing features, not the least of which is it's origin.

It is very rarely that I see fossils from Japan...

yeah, every once in a while someone does a post where i feel that words really can't express what the reaction should be. amazing stuff, well presented, and well described. i'm impressed.

Thank you all for your comments. It is an entertaining little specimen.

Correct "Terry"!, "Qurum" after the mangroves at the bottom of our hill.
