  1. I guess you could rent your own museum exhibit through this page: http://www.angelfire.com/mi/dinosaurs/rental.html Just thought I would share something fun that I came across
  2. Exoskeleton

    Any ideas on names?
  3. ItHi all, Well, we've got large coiled fossil we were not quite sure of what it was found recently in the Permian on the Mogollon Rim. I have had a hard time seeing the right shapes with a concave mold in the coarse limestone, so we decided a final look at the cast would confirm what we suspected as for its identity. It worked! Ill tell you at the end what it was but first I documented the process of filling in the mold in the limestone with white modeling clay as to get a better look at what we had. Here is the huge spiral fossil we wished to cast: First, I wanted to try it on a smaller planospiral gastropod, similar to the one in question. Details are coarse in limestones, and trying to make a latex cast would be a nightmare to remove because of all the fine pits and depressions would make the latex impossible to remove later when it dried. So we went to the craft store and got some pure white modeling clay. If your not familiar with this stuff, it is not the stuff you played with as a kid. Modeling clay feels the same, but is water soluble and will harden rock hard when it dries out. So here is what we started with: The small test fossil was first sprinkled with talcum powder as a release agent. This works very well and is white like the clay. ThisA round clay ball was tore off the big brick of clay in the package ($8 at Micheals) This was pressed into the fossil as best as possible to get the basic gastropod shape: When removedhere - which is very easy with the powder, you get a perfect shape: Out in the sun, here is the result when dry: Well,since that worked pretty well, we started on the big fossil. First the powder: Covered: Then started packing in clay balls all over the fossil: The final load of clay was packed on top to give it strength. It then easily lifts right off, and the cast is carefully laid in a sunny window to dry: And the final result with the proper sun angle two days later was this: So we were able now to confirm what we had suspected all along, this was a huge Straparollus kaibabensis with the nodal bumps on the sides of the adult whorls. The total size was about six inches. So thats it, it works well for fossils in limestone which have little detail and gives you the basic shape. For highly detailed molds in cherts like the stunning crinoids we find in the Redwall, we still use latex. Thanks for looking!
  4. Hey guys I remember the ROM has on display a slab cast of Mistaken Point, Newfoundland fossils on the Dawn of Life Preview Gallery. Being an admirer of Mistaken Point is there a place where we could perhaps get these replicas? Or are collectors allowed to go to Mistaken Point and take casts of the fossils there for keepsakes? I understand no one is allowed to take fossils there due to government laws so I am hoping that casts are an excellent alternative for amateur collectors.
  5. Cretaceous worm casts.

    From the album Cretaceous finds in Western Australia

    These are worm casts I found in the Cretaceous Gingin Chalk of Western Australia.
  6. Short Story I am photographing and cataloging fossil hominin skulls for my college, and I need some help identifying some of the unlabelled casts. I can generally get the species, but I am trying to narrow it down to a specific specimen that the model/cast is based on. Long Story I'm doing an independant study course at college, part of which is to photograph and catalogue all of the fossil hominin skull casts. It's the usual assemblage of Australopithecus through to H. erectus, Neanderthals and then Homo sapiens. However, a lot of the casts are very old and not that accurate, and most aren't labelled. I can generally get the species without too much of a problem, but I am trying to work out the specific fossil specimen the cast is based on, if it is based on a particular one. Also, the college does have some weird and outdated information. They classify the Paranthropus species as Robust Australopithecines, and all they Homo heidelbergensis are called Archaic Homo sapiens. I have taken all the photos, and am sorting through and creating the database. My first step is to label all the photos, export them to a simple folder database. Each photo is titled with the species, fossil catalogue name, nickname, then view. So for example: Au. africanus STS 5 "Mrs Ples" Anterior.jpg. Then I am creating a database of each cast, with all the relevant info (age, location, date found, brain capacity, etc). I am doing this with Bento software, but I plan to export from there to excel, or for whatever software the professors will use. After all of that, what I need is some help with working out which skull is which, particularly trying to figure out exactly which one eg. KNM-ER 1813 or whatever. There are a few, I'll post them up one at a time. Thanks in advance. Mystery Skull Number 1 It's certainly H. erectus, but I'm not certain if it's meant to be of a specific individual or just a general representation. I have seen a reconstruction composed of several of the remains found at Zhoukadian, so I wonder if it is one of those. Or perhaps Peking Man?
  7. Okay, I found these in Mississippi Selma Chalk Formation. Gastropods.... not sure what brand/flavor/species... these are the predacious ones aren't they? Naticacea? Please note: lack of polish. Sometimes I behave, and don't give in to the Lapidary Force... Thanks The Mutt

  11. Anyone Know What These Are?

    Iv had these worm things for quite a while, i found them in a river in the UK, unfortunately i found the fossils broken in 2 in the water but the 2 pieces join together perfectly. Iv been wondering for some time what they are and also what their in as what now is rock must have been some soft substance because they are tunnelling inside what now is rock too, the entire fossil is a V shape, much like if you spread your 2 fingers apart, quite an unusual shape. There has to be over 30 of these things crawling around. Any ideas?
  12. Iwent back down to Fl for a wedding and reception not really expecting a fossil hunt so I was accepting that no matter how hard a pill it is to swallow... We arrived in Mt. Dora area and checked into the hotel. Most of us avid hunters know to look down and around everywhere we go. I saw lots of river rocks in the shrub/landscaped areas. But most will know that a very remote possiblity to find a fossil in there. They did have an spot behind a fenced in area that housed the pool pumps and other pool clorine tanks. This area was locked and there was a layer of chunks of burden from probably a local/state mine. The fencing was similar to a picket type as it had spacing in between the metal pickets. Over the weekend I am sure I got some strange stares as people walked behind me and saw that I was picking up material from the area. I was limited to distance also that I could reach into so improvising I used my flip flops as a tool to reach a little further in and roll pieces towards me. It was not a banner hunt by any means but I came away with a couple nice pieces and got to hunt a little. Also my nephew is into spiritual stones and their meanings and for the reception as party favors he had some Morrocan Calcite geodes at all the tables. I was able to come away with several as some guests left theirs. (more for me) So it goes to show you always look around for any oppurtuninty to hunt.. You never know where you could be..and what you will find. Here are a few pics of what I found first ones are group shots of over all haul..Thanks for looking Jeff
