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 The now outdated view of T.rex being a lizard with poor eye sight and lumbering, is incorrect.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.

Can I please have an ID on these three teeth that were given to me in Tucson when I made a larger purchase?

found some intresting things in my yard... ive found a few pieces like this

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.

Hi! Im looking dinosaurus bones with interesting structure and color like from photo. In return I can offer fossils....

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.

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

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

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.

Hey y'all just started a job on a ranch and they have a very nice theropod trackway. Has at least 10 tracks maybe more. Some are covered by cast off from a mountain. Im fairly sure they are Jurassic but still need to get better gel maps of the area. Anyway my question is what is the best stuff to make a cast of a couple of them. I know plaster of Paris but as with anything is there some new super bad stuff out there? thanks much

So, I haven't gotten a chance to ask about this weird tooth I got in Tucson. The root is there, and in good shape, but I don't think there is any way I can get it out of the matrix. The matrix is solid stone with the hardness of concrete, and I would probably break my tools on it. Youll have to ignore the cat in the background continued

Hey all, I am New to the forum, and very happy to be here with all of you. I live close to Philadelphia, but have been traveling to New Jersey to a well known creek that dates back to the Cretaceous period to hunt for fossils. I found this one thing and I have no clue what it is. Perhaps you'd be able to assist? since I can't post too many photos in the same message, I'm going to add a couple more possible fossils that I don't know how to ID. thanks for having me here everybody! brettco

Just thought I'd share something cool. There's a little rock shop in my city that I like to visit every once in a while. Although most of the fossils they sell are nice little ammonites, orthoceras, shark teeth, etc., they've recently acquired some specimens that blew me away: a couple of solitary raptor eggs, a raptor nest, and a hadrosaur nest! I couldn't believe my eyes when I saw them. I asked one of owners of the shop where the fossils were from and I was told the raptor nest was from Madagascar and the solitary eggs were from South America. I didn't ask about the hadrosaur nest. Questions regarding their authenticity and legal nature immediately flooded my mind as I'm not familiar with the laws of those countries regarding fossils. They also look to me to be incomplete but I'm not sure. Personally, I believe the nests (assuming they're real), should be in a museum or institute where paleontologists have access to study and learn from them, but who could resist the thought of being able to say you own a freakin raptor nest!? Maybe put it on display in your mancave with a plaque that reads: "Dont touch my huevos!" Anyway, let me know your thoughts. Have you ever been in the presence of a fossil that truly astonished you for whatever reason? e.g. your favorite dino, a significant discovery, etc. I'd love to hear your responses.

Well y'all I do believe I found some Dino bone. Sorry it's dirty still but im afraid to handle it much do to the fact I found it near water. It's quit heavy. 50lbs or better. No porous structure visible. Dark black mostly. Well you see the pics. Any help would be greatly appreciated. Great day today considering I found this as well as a nice arrowhead. Well I am getting an error message saying "there is a problem processing the uploaded file -200" anybody have suggestions for a fix? Im dieing to find answers here.

Hi everyone! Just wanted to share with you all this great Triceratops tooth I recently acquired at a very low price! This is the first dinosaur tooth in my collection, and though it's small, I really like it!

This dinosaur fossil is about the about 12 " long and I am not sure what part it is from. I was wondering if anyone could help me identify it.

I took the teeth and and other dinosaur material i won in Grand Christmas auction plus some teeth I already had and put together this display.

Dinosaur fossils 3 Hello I am putting up some pictures of dinosaur fossils I was told some are from Alberta and some from Montana. If anyone could tell by the colors by where they were probably located that would be appreciated. I have included measurement and a couple of pics of each fossil. I will put a few here and make more posts with other fossils on it.

Hello again after 1 year.And sorry again if my English is bad or not enough. It is finally my last year to graduate and start a job as a archeologist. On my free times, i go to beach and try to find some fossils. However,there is nearly no fossil sites in my country and a place which is poor about fossils. I go to beach every day, but all i found is some worthless sand dollars, I didn't have financial situation to travel abroad either. I would like to buy some for my collection.I will love to hear your suggestions. Also, if you can give me some fossil hunting advices, it will be much appreciated. Thank you,

Hello I put up a picture of a fossil I couldn't identify and it worked out so well that I thought I would put some more pics of other ones I can't identify. Any help would be greatly appreciated.

Here is a tooth my colleague found a lot of years near Cognac (Charente, France). It is from a sedimentary facies Purbeckian (Late Jurassic, Lower Cretaceous). The quarry was in the marl, we found many reptiles, teeth and fish scales there, and of very small shark teeth. The size is 4 cm (1" 3/5) Thanks for your help. Coco
