Another Crate

that's quite an adventure on a fossil hunting trip, I guess a lot of us collectors go to car unfriendly places while collecting, I've also had my share of muddy adventures with the car while fossil hunting. 

 

Still, I am amazed that you managed to find something in the snow :D

Glad you had your pickaxe! Looks like a nice Megateuthis there?

I'm glad to hear that you made it out of that tricky spot without too much difficulty, and I'm looking forward to seeing your specimens post-prep...

 

By the way, since you mentioned dreams - two nights ago I had a dream that was searching for and actually found some ammonites on a forest trail - I think my reading of your tales is sticking with me even when I'm sleeping, Roger! :P

Ice, snow, mud and getting stuck and yet you still come away with a nice basket of goodies.  Nice job man.

Well, the car looks a lot better now, since my carwash stamp card has just been filled up, so I could give it the full treatment today for free, wax and all. I did manage to find a few spots with no snow, so I just had to dig in the dirt and bang away at the rocks without having to shovel snow as well beforehand.

One of these days you'll have to bring your family over here and then you won't have to dream any more :)

You could be right, but if so, it's quite a small one. Prep will tell.

Roger the intrepid. Doesn't let snow and ice get in the way of his ammonite pursuits. Congratulations. Nice haul, especially given the conditions. As always- love to see the results once they're prepped.

More niceness Roger!

Thanks for the continuing story.

Your hard-won finds are wonderful, Roger. You'll have to write a ballad about your fossil-hunting adventures someday.

If you check out some of the old poetry contests, you're bound to stumble upon the one or the other from me.

Yes. And he doesn't let commission work get in the way of his private prepping :ninja:. I actually should have gotten back to it today, but I wanted to at least have a quick peek at a couple of easy to prep things and then one thing led to another and I ended up tackling what appeared to be the best ammonite block.

 

@TqB The belemnite turned out to be a member of the Cylindroteuthididae, to be more specific Eocylindroteuthis trautscholdi  from the lower Bajocian discites zone. A first for my collection :)

Excellent! I've not been able to acquire one of those (and I've not heard of them from the UK). Sometimes dealers say they have them but they've so far all been young Megateuthis. It's only the lack of paired apical furrows with slight ventral furrow that characterises them.

Roger, your hunting and prepping skills are unmatched!  Congrats!

Well, I hope it's not just wishful thinking on my part, but I'm pretty sure I can recognize the features on it. Maybe I should remove it from the matrix just to make sure.

@TqB I've removed the belemnite from the matrix. I think I'm correct in my assessment, but I'd still lke to ask for your opinion on this. The rostrum appears to be laterally compressed and is not complete, but I think that the furrow fits the picture more or less. There's no sign of an apical furrow to my eyes at any rate, which would be expected for a juvenile Megateuthis.

Very interesting!  I've never worked properly on belemnites of this age but I don't think it's an Eocylindroteuthis. The furrow looks much too well incised and suggests that there might be something of a splitting surface towards the alveolar end. There's also the suggestion of an epirostrum.

 

I may be wrong but I think it looks like Holcobelus munieri which is even more interesting as it doesn't seem to be recorded from Germany - the linked paper by Robert Weiss et al lists:

Middle Aalenian to Lower Bajocian (Murchisonae– Humphriesianum zones) of France (Mont d’Or, Cévennes, Haute- Provençe, Hautes-Alpes, Normandie, Aquitaine, Bourgogne), Italy (Calabria), Ukraine (Kanev region), Poland and Slovakia (Carpathians), Bulgaria, Romania (Rosia area), United Kingdom (Dorset), Algeria (Hassi Bou Lakhal).

The description is on page 24 and here's part one of the plates - all H. munieri

 

What do you think?

Yes, that is a splitting surface, so I figured if I just ignored it and concentrated on the furrow, then I'd have an Eocylindroteuthis, but maybe that was the wrong approach. Your idea with H.munieri is interesting. I must say, the appearance of this furrow is rather confusing.

@TqB Check out this link on p.156 if you haven't already.

"The venter shows an intermediate narrow depression, which may be more incised and forms an intermediate groove." Etc.

This is trying to convince me that this is indeed an E.trautscholdi.

Glad you managed to get out of that vehicular pickle and get more amazing stuff! Those  Ancolioceras opalinoides are awesome, its always great discovering you've got more than you thought during prep :D

Yes, I was looking at that one too but hadn't read the description which does seem to fit. On the other hand, the figured specimen has a rather faint furrow. 

Belemnites are awkward to ID and furrows quite often misbehave - go back and find some more!
