What is your machine doing?  Can we help solve the problem?  

Thanks for the offer but I dont think so.  About a month ago a filter was blocked because of too fine blasting abrasive and now I have that problem again... So I will buy new blasting abrasive iron powder and send the machine again back to the producer. Hopefully it will work after that ...

Superb work again Sebastian. Feel free to send me the common ichthy fossils :D 

:D :D Thanks John! If they would be common there I would send you some but sadly they arent :P

What are those radiating lines? I suspect it is not fossil or else not something as important as croc bones otherwise you wouldn't have obliterated it!

 

@LiamL already gave the correct answer! I dont really collect ammonites there because they are extremely common (and they are flat :D).

Love to see this material, even cooler to see it prepped. Similar stuff to what i try and find! 

Is Holzmaden matrix soft or quite hard material?

Thanks Liam :) You have indeed more or less the same interests as I! The matrix is very different. For example the "Schlacke" (certain layer) is very hard and sandblasting doesnt really work there (I have some ribs, on which i have this problem). But the "normal Posidonia Shale" isnt that hard and you can prep, for example belemnits fast.

I see what you mean about 'flat' in some of the pieces you posted earlier... But if I were there I know I'd be collecting some of the better, more complete specimens of each taxon. Anyhow you're doing great with the belemnites... Like RJB says they are some of the best I've seen. They look like they're made of metal, like something made in a machine shop!

I suspect he has...As I understand it,  there are basically six species of ammonites found there and in a day you can find all of them.  Ammonites are indeed extremely common at the Kromer pit.

Sounds like my kind of place.  Have these been posted anywhere?

As @jpc already wrote I did that in the past. To be honest: I sometimes cant resist to collect one or two nice ammonites and because of that I have way too many of them :ninja: I started to collect ammonites, then belemnites and now I am concentrating on bones and teeth.

Today I was in the Hauff museum in Holzmaden and I could confirm my ID of the crocodile bones. 

Here is a bad picture for comparison:

I marked one of the crocodile vertebra. It looks very similar to my bone!

 

And here is a picture I took for you Wrangellian:

A plate with many Dactylioceras commune, which is probably the commonest ammonite there.

Here are two more belemnites, which are more or less finished:

 

First one is a 9 cm long Acrocoelites gracilis:

Second one is a 14 cm long Acrocoelites, which is one of my personal favourites:

Here you can see one of the three apical furrows:

Ah, that's what one of the real, unaltered plates looks like, is it? I've got a small one from online seller that appears to be doctored up (below) - the larger ammos appear to be artificially colored and the whole piece is coated in some kind of wax.

I know what you mean - I'd be always tempted to collect any nice example I came across even if I already had many of them. I do that already with certain things from my local site, but they are mainly small bivalves - the only thing that's really abundant.

wrangellian-I don't think yours is too doctored,  The color is natural.  The beeswax, OK, that is doctoring.

Thats actually a very nice specimen :) And the colors seems to be natural indeed. 

 

Here is one of mine for comparison:

On mine there are many smaller ammo's that lack color completely - see for instance the one near the middle-right edge which is almost the size of the colored one near the bottom edge but lacks color... I can't imagine why only some of the larger specimens would have color except that someone added it to make them stand out from all the smaller ones. Anyway I like your unaltered/uncoated specimen better!

Ok then the picture is maybe a bit intriguing! And thanks :)

 

I am still not able to prep because of my tools and because of the lack of time at the moment .... ^_^

I don't know, I look at my specimen and it could be real (aside from the wax) or it might be enhanced. I can't decide. I thought one of them had scratch marks as if someone tried to enhance the ribbing after slathering them with paint, but that could be the actual ribbing. Again, I can't tell. Is it possible for some ammo's to have that color and others not, on the same plate?
