  1. I can't travel far at the moment so all my hunting for the past couple of months has been in a local Lower Carboniferous, Asbian aged freshwater lacustrine deposit, the Burdiehouse Limestone. This is one of the most laterally extensive beds in the Midland Valley of Scotland and luckily theres a few good eposures of it nearby where past quarrying has left some nice productive spoil heaps. I'm always hoping for complete fish when hunting in this bed but none have turned up so far in the recent hunts. I have been lucky on the tooth front though and came across my first lungfish tooth plate from this bed which I was really happy with The petalodont tooth Ageleodus pectinatus has been the most common find. These were some of my favourites, they range from 3mm to 6mm. I've also doubled my collection of these little Xenacathid teeth but I'm still not sure exactly what genus they belong to. They're pretty tiny little things, the larger of these two is 4mm and the smaller only 2mm. Holocephalan teeth are really rare in this formation so was very pleased with this one, its the largest Ive found so far at 6mm. Not sure of the ID but thinking some sort of Helodontid. The lungfish tooth plate, its still attached to the mandible and the whole thing is only 5mm long! Think its probably a Ctenodus sp. but not sure.
  2. A couple of summers ago I found what is maybe my favorite Mississippian/Lower Carboniferous Visean shark fossil in Fife, Scotland and with some time off over the holiday season and pretty grim weather I've finally got round to prepping it When I found it there were three damaged but very near complete large Saivodus striatus teeth, the root minus the central cusp of either a smaller S. saivodus or possibly a Cladodus mirabilis and a partial unidentified spine. I've exposed and restored the three big teeth to make them look complete again as best I can for now and exposed the rest of the root of the smaller one but will leave it as is along with the spine. Unfortunately I cant find the original pic of it as found but originally the tooth on the far left was missing the tips of the lateral cusps and the central cusp from about half way, the middle tooth was missing about half its root and one lateral cusp, and the tooth on the far right was missing a chunk out of one side including the lateral cusp and the opposite lateral cusp. I used resin for the restoration which I carved and then painted with water color and acrylic paints and finished the cusps with a coat of gloss varnish and the roots with matt varnish. I'm fairly happy with the restoration, it does seem to look quite a bit better in real life as photos seem to show up the restoration a lot more. The teeth are on a nice big block I've cut a base on in a thin layer around what seems to be a ball of clay with calcite infilled septarian cracks again, there's a few different types of invertebrate such as bryozoans, crinoids, brachiopods and a nice coral which I love finding teeth with as it gives them context. The block is 14cm tall and the teeth are all 2cm x 2cm.
  3. Hi again! Two more ID requests - this time they're from the Bangor Limestone in Alabama, USA (Lower Carboniferous, Mississippian). Specimen #1: An orthoconic nautiloid - could it be Brachycycloceras sp.? Specimen #2: A blastoid - Pentremites sp.? Thanks for your help! Monica
  4. Hey everyone, been meaning to post this paleoniscoid fish here that I found way back in 2011 and finally got round to properly prepping a few weeks back. It was my first complete Carboniferous fish from a site in my hometown and definitely still my favorite! When it split out the head, tail and fins all stayed on one half of the split and the body on the other. I cut the body out and stuck it down as tightly as possible and used a combination of acetic acid and a needle under a microscope to slowly expose the scales, really pleased with the result and might attempt it with more fish now! The species has been identified as Elonichthys robisoni and it was found in a Lower Carboniferous, Visean, freshwater limestone deposited in a shallow lake in a basin that is now the Forth Estuary. This species is the most common actinopterygian in deposits of this age in this basin. The object behind the fish's head is a coprolite which this bed is crammed full of, this one is on the smaller side but it is probably rhizodont. You can also just see the edge of a sand injection to the right of the fish going off the plate, glad this missed the fish or it would have cut right through and distorted it!
  5. Not had a chance to get out hunting much for a while but had a trip out to a new site the other day and found some brand new stuff I wanted to share! Just outside of the little coastal town where I stay in Fife, Scotland there's a Lower Carboniferous stromatolite bed known for its beautiful stromalolite formations in a hard cream colored limestone which can be cut and polished for use in jewelry. This stromatolite bed lies on top of Lower Carboniferous lava's and has been correlated with another, 30m above a bed called the Burdiehouse Limestone which I do a lot of my collecting from. This puts its age somewhere in the late Asbian. These stromatolites grew in a freshwater lake that had formed on cooled lava flows. Its a challenging and dangerous site to collect from on an extremely steep and crumbly wooded slope below cliffs, very quickly though I started to find beautiful fragments of the stromatolite bed as well as a completely weathered out example and lots of split-able limestone with the occasional fish scales, freshwater bivalves and microconchids. The real prize of the day though was a beautiful and perfectly intact Petalodont shark tooth just lying on the surface of a massive block of the stromatolite bed, this stuff is so hard and not bedded at all so the luck involved in this being broken out like this is staggering! Not sure of the ID of the tooth but think it may be a Petalorynchus sp. Its 19mm from the tip of the crown to the end of the extremely long root. This was the first thing I picked up, a small stromatolite that had weathered out of the formation almost perfectly intact.
  6. A most unusual blastoid

    Hey everyone, long time no see! Last week, my historical geology class went on a field trip and did a little fossil collecting, so naturally I've had the fever ever since. A couple of days later I decided to hit a nearby roadcut and do some nosing around. After a few hours I had collected some very nice echinoderm material (including a nice Taxocrinus crown), some of which I am not totally familiar with. What I thought to be my most unusual find was this weirdo little blastoid. The first thing that struck me is the rust color, I've only seen this in my Floraville blastoids, and those are just slightly rust-colored, not covered head to toe like this little guy. You may not be able to see this in the photos, but there appear to be some pseudofossil markings on one side. Another strange characteristic is what I'm going to call the arrangement of the plates, could it be that this thing didn't get to 'close itself up' all the way before it was buried? (I do not study biology or paleontology so please stop wincing) If not, I'm wondering if I found one of the less common species of what I assume to be Pentremites. Of all the blastoids I've found, this one is probably the most unique, if someone could help me ID this thing it would be greatly appreciated! If additional photos are needed, I will gladly provide them. Thanks, Matt P.S. I apologize for the poor lighting in the photos (and for the lack of scale!), it's very hard to get a good picture in my half-subterranean apartment that only gets direct sunlight early in the morning. P.S.S. Hats off if you picked up on the Twilight Zone references.
  7. Day Two ; Locality One (or Six if you include Day One) Black Sahara, South of Erfoud 20th February 2019 Well this is where things really get interesting, so stick with this thread as there are dozens of photos of fossils coming up. Looks at the tags if you want clues. I was up bright and early and wandered out at about 7 am to watch the sun rise over the still mighty Erg Chebbi dunes. And as night's candles were burnt out and jocund day stood tiptoe over the misty duney tops, the chaps came to join me and managed lots of photos. Here's one, if you would like to see more, I'm busy posting a kazillion of 'em under the Nature Photography thread.
