25cm. Early Jurassic Sinemurian. From the Wutach area in southwest Germany. I didn't find this myself, just did the prep work, but it turned out so nicely that just had to post it here. -
I took a walk over the fields yesterday in the Wutach area. The farmers are preparing their acres again, so it was time for a stroll. The sun was shining, so I didn't get all that much muck on my boots, but nevertheless, I'm having to vacuum the driver's side of the car today. There wasn't all that much worth keeping this time around, but I did hang onto this one. A Myophorella clavellata bivalve with a length of 8cm. They're not at all common in our area at this particular Bajocian stratigraphic level, so I was glad to have found my third and best preserved one in about 10 years. It's missing a bit from the end, as indicated in the second photo, but that's not so important. The second one is a recent gift from a friend who says he has enough of them, but I just can't say no to a nautilus, although I already have about 50 of them. It's just the very inner whorls of what probably had originally been a pretty large Cenoceras sp. from the Sinemurian, but I think it's pretty cute at 5cm. diameter.

9.5cm. Partial phragmocone. Calcite steinkern. Parkinsoni zone, late Bajocian. From Burton Bradstock, Dorset, UK. -
A small specimen with most of the body chamber intact.
-
Calcified steinkern. Phragmocone plus a bit of the body chamber.

This is part of the phragmocone in steinkern preservation. The siphuncle can be seen in the second to last photo. The last photo shows a large specimen with body chamber (22cm.) and a smaller one, which is just the inner portion of the phragmocone (4cm.). Both are from the same site and zone as the first one.
