  1. A few of my ammonites collected from the Inferior Oolite at both coastal and inland quarry sites in Dorset, UK.
  2. Stabilising Dinosaur Footprint

    Hello everyone, I have a question regarding stabilising sandstone to keep it from crumbling. Last year I found and extracted a dinosaur footprint from a block on the beach at Whitby, Yorkshire UK. The footprint is of an Aalenian age therapod from approximately 170 million years ago. The print itself measures 20cm from the base to the tip of the centre claw mark. I am hoping to get the block it is in cut down into a slab in order to frame it but now that it is dry the sandstone is very loose and crumbly. I am looking for something that will add strength to the stone and prevent crumbling without significantly changing the colour of the stone or adding a shiny finish as I would like the finished piece to remain as close as possible to how it was, just stronger. I was hoping somebody would have an idea what would be best to soak the block with in order to keep it from falling apart. Any and all suggestions are greatly appreciated. Thank you, Benton Walters

  5. Twins

    I recently recieved a very interesting block with two ammonites of the same species to prepare on commission which I would like to show you here. They lay about 10 cm. apart one over the other, so either they were imbedded at different times or else they reached their final positions through turbulence. Staufenia staufensis is the species, one having a diameter of 18cm. and the other one of 16. They come from the Middle Jurassic bradfordensis zone of the Late Aalenian. I'll show you the progression of the preparation using 4 blocks of 4 photos each showing different perspectives of the block. The first thing I did was to rid the block of as much excess matrix as possible with hammer and chisel, but I didn't think to take photos of the original, so the first photos to be seen are the ones taken after that. Below is the state after a few hours of work with the styluses. It's starting to get into shape now. Then I spent the next few hours abrading and fine-tuning the shape with the styluses, rocking back and forth between the two as necessary. ...Looks like I'm going to have to make another post...

  8. I mentioned in another post a few days ago that I had discovered a site in the Middle Jurassic Aalenian which I hadn't visited previously. I found it rather unexpectedly while in search of the humphriesi oolite formation. It was obvious that other collectors had worked here in the past, but the rock had also been weathering away for a few years since the last ones were here, so I figured it would be worth spending the good part of a day inspecting it. I set off to this avail this very morning. It's a bit of a way up to get there, but not too strenuous if you take your time. By the way, I remembered to take my camera along this time, so here's a shot of the exposure. I spent about 5 hours working at it but ended up digging out a lot of partials since the stone was extremely hard at the one productive horizon and too soft in the other one. That's the luck of the game sometimes. You can always find the right horizon once you've located an exposure, but the preservation is often quite different than at other exposures not too far away. Here are pics of the 2 spots I was working at. It wasn't all for nothing at least, since I did manage to salvage a good sized Staufenia staufensis ammonite out of the hard horizon. This is how it looked before I maneuvered the 2nd block out of the bank. And here are both pieces ready for transport. Looks like I've got a bit of prep work ahead of me. There were also a few smaller ones to take with me. So that was it for the day. Downhill is always as easy as pie and a stop on the way home for a rump steak with scalloped potatoes and a red bull is the incentive that gets me out in the first place I'll post the finds later on once I get down to prepping them.

  10. A hike through the Wutach

    This past Sunday, I decided to pay my friend a visit at his workplace in the Wutach valley which I reported on recently. I left home a few hours earlier than he did since I wanted to visit a site on the way which another friend had told me about. This was off of a steep path through the woods which I had never taken before, so I was looking forward to excercising my calves and thighs. The way took me a kilometer or so uphill until I reached what appeared to be the pinnacle, which was where the exposure in the humphriesianum zone was supposed to be which I had been looking for. Up to that point I had hardly noticed any exposures, so I was happy to discover an approximately 20 meter long one here just below the path. Downed the knapsack, pulled out the tools and went at it. After a few minutes, however, I noticed that I obviously hadn't reached the highest point, since I was digging in the Aalenium, the epoch where I feel most at home, so it works like a magnet on me. Surprise, surprise. Funnily enough, I ended up making my best finds here. Spent about 2 hours prying away at well-weathered rock which obviously had not been touched by collectors for a good long time. I think I'll come back soon for another visit. Anyway, I carried on afterwards up the hill and eventually found the exposure I had been originally looking for. Spent an hour or so exploring it, but didn't come up with any ammonites as I'd been hoping. Did find a nice bivalve however. After I was done there I headed on over to my friend, a brisk walk of a couple of kilometers through the woods over flat land. Just a bit of downhill slipping and sliding at the end to get to him. Good thing I could hear him hammering since it wasn't all that easy to orientate myself for all the trees and shrubs. Then I just relaxed, drank a lot of water and watched him sweating at it. He'd had enough after an hour or so, so we made our way together down to his car and he drove me back to mine, which was a welcome relief for me. Here are the finds I made, already prepped and finished. The first is a Ludwigia haugi, my avatar, the next ones are Ancolioceras opalinoides and finally the bivalve from the humphriesi oolite, a Ctenostreon proboscideum.

  24. I made another visit to that site in the Middle Jurassic Aalenian to continue on where I'd left off last week. Here's the original report . I headed back up to the exposure with the intent of continuing along removing more of the weathered blocks from the bank. But first of all, I noticed a possibility to remove a bit more overburden from my dig last week. Like I'd mentioned before, this overburden belongs to the so-called staufensis bank and there's always a chance of finding something in it, although they are few and far between and not always complete. But waddayaknow! I uncovered a Staufenia staufensis ! You can't see it all that well in the first photo, since most of it is still inside the matrix, maybe a bit better in the second one. I had just dug out the missing piece of the venter and took another shot. I banged around a bit more, but soon gave up when the going got too tough. Then I turned my attention for about half an hour to scraping away the dirt and rubble in front of the weathered blocks. Then I started hammering and prying out the blocks, starting as usual at the top. It didn't take long this time before the finds started showing themselves.
