  1. Gday all, this is my Edmontosaurus collection so far. Most of the bones here are from the left foot of an Edmontosaurus but there are a few other pieces, rib sections and teeth. I'm trying to build a complete left foot, originally I didn't set out to do this but I bought a few toe bones and soon realised that the majority of them were from the left foot so I decided to turn it into a project. It will take me some time to source the correct bones but that will also give me some time to save for them! I have a few bones that aren't right, for example met 111-1 is the correct bone but just too small so I need a larger one to keep everything in proportion but waiting and searching is all part of the fun. Thanks for looking, Dave.
  2. I found this 2 3/4 spinosaur tooth being sold on a popular auction site. It looks like it's been painted to hide enamel peel. About how real is the tooth?
  3. Very nice variety The cut dinosaurus bones fragments. Size is betwen; smallest one 3 cm and bigest is about 6 cm.
  4. Hi guys, On a auction website I bought a collection of small Dinosaur/ Mammal fossils from the Lance Formation in Wyoming. First photo: Have you any idea which teeth belong to what dinosaur or Mammal? And is the central left piece an crocodile scute? Second and third photo : Is it true, this could be an Ankylosaur scute? thank you very much!
  5. Hi, I bought this claw in Rissani, Morocco for a week ago. It was found in the Kem-Kem area. But I'm not sure the species it belong to. Any suggestions?
  6. Hi TFF, I have this dinosaur claw from Hell Creek. I purchased it a couple months ago and now I have noticed something I didnt really notice when I first got it. Its like hair- type stuff in the fossil itself. I thought it was just from the riker box it was in but when I tried taking it off, it was like it is part of the claw. Was just curious if you guys know anything about it if its is fungal or something. And how to take the stuff completely off it. Thanks guys and for the replies.
  7. Has anyone ever been to the Sainte Marie Aux Mines gem and mineral show? How is the fossil material, specifically dinosaur? Worth a trip from the US?
  8. Hi everyone...I have taken these two teeth from Morocco that should be of Spinosaurus. Any information is accept. Thanks
  9. Is this a tooth of Richardoestesia isosceles? Scale marks on left side of tooth are in mm and on the right side are in 0.5 mm increments. Serration count ranges from about 6 to 8 per mm. What remains of the tooth is approximately 11 mm in length. Hell Creek Formation (Late Cretaceous: Maastrichtian), South Dakota.
  10. Hi guys I recently got sent a package from some friends for my birthday which included some nice little goodies including tickets to see the Dinosaurs of china event in Nottingham this summer, Included was this lovely piece identified as purely teeth and bone from a Hadrosaur which was found in the Lance Formation, I was just trying to get any information regarding a species level is possible? I'm not entirely sure if this is possible but hopefully you guys familiar with the lance formation fauna may help. Many thanks, Chris.H
  11. Looks like we will have a new book describing Vertebrate fossils from the Hell Creek Formation courtesy of the paleontologist Thomas Holt and others. What I heard is that the publication is scheduled for this fall, no idea of price. I was able to get a hold of a beta copy while visiting one of ranches I collect on and took some quick phone pictures. I had several reactions when I read the book, the dinosaur section getting poor grades while the other sections were informative. It was the first publication that covered vertebrates other than dinosaurs. The information shown was very descriptive and covers finds collected by the authors group since 2006. The books weakness is that if it was not collected it did not make the publication and the authors did not look to supplement the information. The other weakness is that the photos used were that of the actual pieces collected in what ever shape they were in. For example, they are providing you a guide to an Ornithomimid hands claw only showing you a half of a claw. Here are some pages from the book. Covers fish, lizards, salamanders, crocodiles and dinosaurs. The best part of the dinosaur section was the descriptions of Thescelosaurus foot claws and teeth which I will show on another post. Theropod teeth shown were poor examples and not every species covered. No mention of Nanotyrannus since this author does not support its existence. So the best use of the book is for trying to ID fossils other than dinosaurs from the Hell Creek or Lance Formations. A book that is not all encompassing but few are and should argument other reference material. I will probably purchase this book for my reference library I was appalled at the statements in the front of the book. Most collectors do not have an opportunity to collect this fauna and their only way to enjoy Hell Creek material is to purchase it. Are the writers of this book on such a high pedestal that they look down on everyone else. So who is this book written for? I'm happy to know that the theropod paleontologists that I'm familiar with support and work with diggers and collectors to gain a better understanding of the mesozoic era. Let see what the published book contains this is only a beta version. @LordTrilobite I did scan the book to see if your vertebrae were shown but no luck. Guess they did not find any. REMINDER: This information us from a beta version so it's subject to change
  12. This is a Profile on the T.rex that I had written for English and would like to see what you all think and correct me on what is wrong about it! Tyrannosaurus Rex is one of the most famous of all non-avian dinosaurs to ever roam the earth, and is known by the name T-Rex. Well that is an incorrect wording as the correct way to write the animals name is T.rex. Very few people know this and is one of my life dreams to educate people about this. Tyrannosaurus means Tyrant Lizard king. The now outdated view of T.rex being a lizard with poor eye sight and lumbering, is incorrect. In all actuality Tyrannosaurus rex was a warm blooded feather coated bird that could run to 25 miles an hour and actually had the best eyesight the earth has ever witnessed with eye sight over 13 times more clear than a humans. The first clue of this is the fact Tyrannosaurus had front facing eyes, meaning it had perfect depth perception. We know this because of the recreation of the eyes based on the fossil skull, eye sockets, which indicated its eye was the size of a softball. T. rex’s binocular range was 55 degrees which is actually greater than that of a hawk, which is of course renowned for its remarkable vision. Mix this eyesight with a sense of smell better than a bloodhounds, and a complex bird brain, this would be a perfect predator. Tyrannosaurus needed all these advantages as its pray was far from defenseless. Its pray would have included Ankylosaurus, Triceratops and Hadrosaurus which all have hard armor or a thick tail to ram into the predator to hit it off its feet. Tyrannosaurus rex lived in North America about 70-66 million years ago in the Hell Creek formation that leads from Montana to Colorado and branch off into Utah and Canada. During the time of Tyrannosaurus, the Environment of Hell Creek was a flood plain, creeks, swamps and dry forests of conifer trees and ferns that dominated for millions of years. The Swamps were home to many creatures such as crocodiles, fish, lizards, small non-avian dinosaurs, amphibians, mammals and birds. Away from the swamps, you would find dry forests and plains, which had creatures such as Tyrannosaurus, Triceratops, Dakotaraptor, Pachycephalosaurus and an uncountable number of others, not including the thousands of plant and fungi species. Meanwhile giant pterosaurs roamed the sky, and giant marine lizards swam the oceans. All of this was the domain of the mighty Tyrannosaurus rex, an invasive species from Asia that came to America during the early cretaceous period through land bridges and shallow seas. They became the top predator, and knocked other predatory theropod dinosaurs off the throne of Top Predator. Tyrannosaurus, despite popular belief, was covered in soft downy feathers much like emus and ostrich. They only really had scales on the under side of the tail, while their legs and face would have skin like an ostrich leg. They also did not roar, and most likely cooed and/or quacked like a modern day bird. They cared for their young like a mother bird and would defend them from anything. The closest living relative of the Tyrannosaurus is now the Chicken, and it may surprise you to know Chickens can chase, catch and devour mice whole, much like the Tyrannosaurus assumingly. For the very last thing you need to know the T.rex comes from a group of animals called the Tyrannosaurids, this group includes the Dilong, Gorgosaurus, Albertosaurus and Tarbosaurus.
  13. Can I please have an ID on these three teeth that were given to me in Tucson when I made a larger purchase?
  14. found some intresting things in my yard... ive found a few pieces like this
  15. From the album My Collection

    This is one of the shelves in my display case. It features what little dinosaur material I have along with material from other reptiles (mosasaur, keichosaurus). There's also a branchiosaurus in there for good measure.
  16. Please be aware there's a bunch of supposed Ankylosaurus fossils on our favorite auction site. They are sold as Ankylosaurus armor, or tail plates. There are other similar pieces of maybe-fossils sold as Ankylosaurus parts, along with pieces of rocks sold as dinosaur eggs. I admit my knowledge in Ankylosaur fossils is limited, but I see absolutely nothing about these that's indicative of authentic Ankylosaurus fossils. No locality is given either. Please be on alert when you see these, along with the sellers' other suspect items. Real Ankylosaurus fossils should firstly be sold by a reputable dealer(since they are hard to identify properly), they should have bumps/ridges indicative of armor, and should have a rugose/wrinkled/bumpy texture. They are found in the Hell Creek Formation, Lance Formation, and Scollard Formation. Here are pictures of 4 authentic specimens for your reference.
  17. Hi! Im looking dinosaurus bones with interesting structure and color like from photo. In return I can offer fossils....
  18. This may seem to be an unusual question from someone who is a "budget" collector of dinosaur fossils, but for a project of mine I'd like to gradually acquire a collection of some large mammoth or dinosaur bones for public display. However, they still need to be relatively inexpensive, under $150 US. So my question of this: Are there any large bones (requiring two hands to hold large) that can be acquired for a relatively inexpensive price? I know mammoth bones can be pretty cheap (especially North Sea) but I'd only buy from a seller who properly desalinates them. Does anyone know of a dealer who supplies this kind of material? PMs welcome and thanks in advance. As for dinosaur bones, it's probably a long shot, but I know that some time ago some larger bones (rib bones and limb bones as well as vertebrae) used to be pretty inexpensive. Does this still hold true? Thanks.
  19. Hello I have recently inherited a small collection of fossils. I was wondering whether anyone could provide me an ID for these three similar items. Best wishes
  20. Hi guys I recently acquired a nice Vertebra from the Isle of Wight from someone I know. It was found in yarvaland and comes from the Wealden. It's Cretaceous in age. It was labelled as polacanthus but I'm unsure if it is and the price was quite cheap so I went ahead just wanted to check in case it's an Iguanadontid Vertebra instead so I can relabel. Many thanks for looking GK
  21. Here is another peice of my work, this profile is on the Stegosaurus and once again I would like to see what you all think but keep in mind I kind of wrote this in a biased way, as in I used the theories I think are true without mentioning other ones so Forgive me for that. But hey, At least it's pretty simplified. Stegosaurus is one of the Most well known of all dinosaurs along with the T.rex and the Velociraptor. Despite this very, very, very, few people know what it actually looked and behaved like. For example the Stegosaurus has Sexual Dimorphism which means a difference in the males and female's. Females have sharp pointed Plates along its back while the males back plates would be rounded kind of like a squashed circle. Stegosaurus is part of the Stegosauri family that arrived on the scene in the early Jurassic and died out at the end of the Jurassic Period. Stegosaurus grew to be 30 feet long and 9 feet tall which 3 foot long plates and 3 foot long thagomizers which were the spikes at the end of the tail, that it used for self defense. Stegosaurus has extremely small heads even for a Stegosaurs, They fed on Fern cycads and Conifers which were the dominant plant species in the Jurassic period in North America. Another thing, Stegosaurus is native to North America in places such as Wyoming and South Dakota along with animals like Brachiosaurus and the Brontosaurus Stegosaurus also have a thick armor on its neck represented by thick rock like scales. While the bone plates and thagomizers in the skeleton are large, they were much larger in life as they were covered in keratin and thick sponge bone like material. It's notable to mention that Stegosaurus tail spikes called thagomizers are at the tip of the tail and unlike many archosaur tails which get thicker and stiffer near the end instead are very flexible like the tail of a monkey in order to swing around their thagomizers with great accuracy against predators, killing a Allosaur in one blow or at least wounding it badly. Fossil Records of Allosaurus show puncture woulds in areas like the leg or against the pubic bone which is part of Pelvis. These were caused by the Stegosaurus which was defending itself or a baby, Now while they have these large spikes to protect themselves they also have these large kite shaped sponge plates which were not protection but was used for Courtship for females and to confuse predators, This means it would flush blood into its plates and they would turn to bright red along with other colors, the body would likely be green or brown while the plates would have bright colors much like a Baboons Colorful face. Stegosaurus was discovered by the Famous Charles Marsh in 1877 and Stegosaurus had this very wide gap of space in between its hips and Marsh thought in this space it had a Secondary brain. Now he thought this because this elephant size animal had the brain the size of a dogs brain. He thought this was not enough and he had to had a secondary brain to help it function. Not true it did not have a second brain and no dinosaur or reptile ever had a second brain.
  22. Hello, I picked up some Hadrosaur skin on auction last week and not having much experience in skin I'm hoping someone can comment on its authenticity? Thank you
  23. I have read many of Dr. Schweitzer's papers and am wondering what the safest methods to extract soft tissue from dinosaur bones are. I cannot find any information on this topic so I figured I would start here. By soft tissue I mean apparent original biological molecules such as collagen, red blood cells, etc.. Thanks for any help on this topic!
  24. From the album Jurassic fossils from the Newark Supergroup

    Theropod Footprints- The top two digits are from one individual. The bottom digit was buried by another facing in the opposite direction. Jurassic Period East Berlin Formation Newark Supergroup Middlefield, Connecticut A gift from Tim (fossildude19). Thanks again, Tim.
