Another Prep Job


Ludwigia

Recommended Posts

I think I mentioned in another thread recently that I'd managed to find the block with half of the ammonite in it which had promptly tumbled down the hill after I'd just pried out of the cliff in the Wutach valley. It took a good hour, but I was determined to find it, since the half which had stayed put was telling me that this could very well be a good 'un. The block was pretty large and heavy, so in my attempt to reduce weight and size, I managed to also make 2 smaller blocks out of one. Nothing went missing, so it was ok in the end and a lot lighter to tote. Here's how they looked after I got them home. The first pic shows the exposed ammo bits and the second how they looked when pieced together.

I decided to glue the 2 smaller pieces together and have a go at that side first with the air pen and a bit of abrading just to ascertain the position of the outward ends of the ammonite and to clean up the broken edges without losing anything. I placed them together again for the next photo.

The procedure was then similar with the larger block. Again placed side by side for the photo.

The next step was to work separately on each piece mainly with the abrader, although I used the pen a lot in order to get the inner whorls free.

Then I chopped away a lot of matrix from the left hand side in order to give it a more balanced form, gave it another once-over with the abrader and only then glued the 2 halves together.

Not quite finished, since I still had to fill in the gaps and cracks with stonemeal. You can see it in the final result, but I think I'll leave it this way this time instead of trying to camouflage it. The ammonite is a Staufenia staufensis from the local staufensis Bank of the upper Aalenian. It has a circumference of 20cm., although it's not quite complete and would probably have been at least 5 or 10 cm. larger.

Awesome job. I find myself scrolling from the top to the bottom- looking at the "before" and "after."

Beautiful work Ludwigia - you would definitely need experience to see the potential in this piece and coax out its beauty.

How long have you been prepping ammos ?

WOW- that must have been quite a task-- and another prep that is well done. The end result looks amazing!!

A great fossil and a great Photo essay. :goodjob:

Thanks guys :)

I guess you could compare it with feeling your way through a crab concretion. A knowledge of the anatomy of each species is a must. I've been prepping for about 15 years, although I just aquired my "heavy equipment" 5 years ago.

What sort of heavy equipment do you use? Do you mean pneumatic chisels like a mighty or super jack?

Thanks for sharing the 15 years of hard earned experience with us.

Hi Roger

Very nice. Did you prepare the halves separately because of the weight?

By the way, I was in Germany the other day and wanted to do some fossil sites but didn't have time. I did manage to go to the Berlin Museum of Natural History and saw the dinosaurs collected as part of the Tendaguru expedition which was fascinating.

All the best

Wow Roger! I don't know how you do it. You some how brought that thing back from extinction. From your first picture, it didn't look doable. Brilliant prep, sir.

Well, partially I would say. The pieces are a lot more handy when they're smaller, but I also like to see exactly where they're sitting in the stone before i join them all together. The Berlin museum is great, isn't it? Pity you didn't get around to some collecting. Maybe next time around.

Super cool to see all the pictures from start to finish. Nice work.

Thank you both for the positive feedback.

Carrying along on that note, here are a couple more that I've just finished prepping.

post-2384-0-39893300-1431985067_thumb.jpg

Ludwigia bradfordensis deleta. 7cm.

post-2384-0-09252800-1431985152_thumb.jpg

Ludwigia haugi. The large one measures 12cm. It's complete and almost all of the shell is intact. I really love this one. It took about 12 hours to get it out of the matrix, but it was well worth it.

Thanks Tony, but to be quite honest, many of the ammonites that I've seen in museums could do with a good prepover.

Hey Roger, appreciate seeing the steps to put a great find back together and skillfully prep it...

I need some real tools!!

I wholeheartedly agree. My experience has been that museums have to rely on volunteer labor for the most part. Many of the volunteers don't have anywhere near the requisite skills or experience. But, the museums can't afford to hire professional preparators.

OK already ... that is the quality that We would like to see and should be standard for specimens in a museum!

I was just trying to say I think it is a very good prep!

Thanks Chris. It's true. A whole new world opens up once you get this equipment and if you're serious enough about collecting, then it's well worth the investment.

Sad but true in many cases.

Hey Tony, no offense meant. That was just my strange Canadian humor shining through.
