  1. Amazing day yesterday! @sharkdoctor and I spent all day at the Calvert Marine Museum’s collection sorting through and cataloging pieces of his collection either loaned or donated to the Museum. When I say amazing fossils, I mean it. Crabs, birds, whale material, possibly a new species of seal, teeth, turtle plates, and more. @sharkdoctoris a really cool guy because he focuses all on adding to science and not just trying to grow his own collection. Plus, he’s so informative! After completing the cataloging of his collection we proceeded to catalog some of Bretton Kent’s world class shark tooth collection. The incredible John Nance took us through the museums archives, showing us the only Hexanchus from Calvert, 3 inch makos, Gomphothere Teeth, rare species of shark, a whole crocodile, and other innumerable fossils that would be any collectors dream to have. Thank you John Nance, @sharkdoctorand the whole fossil community for building this up.

  5. I keep thinking I must just be stupidly forgetting/overlooking something, but I haven’t been able to come up with it in a long time. There were birds during the Mesozoic(hesperonis, for example), long before theropods evolved into birds(after the Mesozoic, right? I thought all the already very bird-like Dino’s, like archaeopteryx, dead-ended at the end of the Mesozoic)....what am I missing, here? I’ve been looking at bird evolutionary charts, and none of them seem to make sense of that. I’m not all that learned on this topic, but there are things I at least THOUGHT I knew about it, but I’m now very confused because of it, and questioning how much I really DID know! This is is just another thing that’s caught my eye, that seems strange. I’ve always thought this wasn’t the case, but as I’ve said, I’ve never known very much about this whole subject. According to the charts I’ve seen that specify this aspect, songbirds and most birds in fact, are more closely related to the first Dino/birds than raptors are(hawks/eagles/falcons). Are raptor really some of the furthest related to dinos(seemingly in the furthest 15-20%, or so)? Lastly, I’m having a very hard time finding information on terror bird evolution, and where THEY fall within the bird tree. Is anyone familiar with that?

  10. On Sunday I took a trip to the Natural History Museum in London. I queued up before it opened at 10am and even before then there was a long queue. I have not visited this museum since I was a child and spent an entire day there (10am to 4.30pm - a long time). I was surprised as it is a lot bigger than I remembered and there was so much to see. This place has the most wonderful things and is an incredible place to learn. The museum showcases a Baryonyx, Sophie the Stegosaurus (the world's most complete Stegosaurus) and more! The moving Trex and Deinonychus are also really realistic in the way they move. If you like your dinosaur teeth, the Megalosaurus and Daspletosaurus teeth are out of this world! There is something for everyone in this museum and I would highly recommend that you visit here if you have not already! A lot of the dinosaur specimens are casts taken from other museums but they are still cool to look at. I had taken the photos on my SLR and due to the size of the photos I had to reduce the quality of them to be able to post on the forum which is unfortunate but it's the only way otherwise the photos would take a really long time to load. There are more non-dinosaur related photos that I will be posting at some point later on but may take me some time to pick out. Enjoy the photos from this section of the museum!

  14. Dinosaur and Bird Fossils Returned to China

  15. Genuine fossils with exquisitely preserved plumage from the Late Jurassic and Early Cretaceous of north-eastern China have recently revealed that bird-like theropod dinosaurs had long pennaceous feathers along their hindlimbs and may have used their four wings to glide or fly. Thus, it has been postulated that early bird flight might initially have involved four wings.

  19. The amazingly preserved fossil. Peteya et al./Palaeontology Many birds today are famous for their beautiful plumage, whose iridescence is often used to attract a mate. A new study in the journal Palaeontology has revealed that the very same seductive sparkle existed in at least one type of bird living hundreds of millions of years ago. Excavated in northeastern China, a juvenile critter – no more than 8 centimeters (3.1 inches) in length – was found with its feathers immaculately preserved. They were long and streamlined, and spread out from its back and tail, leading researchers to think that it may have displayed them in the way a peacock does. In addition, intricate structures, those used by modern birds to warp the passage of light to produce reflective and colorful patterns, were also spotted within the feathers. This combination of evidence suggests that this bird used these feathers not only to aid flight, but – like plenty of birds today – they were also used to show off to an eligible singleton. This particular 120-million-year-old airborne dinosaur was part of the extinct enantiornithines group. Almost all of them had clawed fingers on their wings and many still had teeth within their “beaks”, but externally they resembled modern birds. “Many enantiornithine birds possessed ornate feathers,” lead author Dr Jennifer Peteya, a palaeontologist at the University of Akron, told BBC News. “This new specimen shows that some enantiornithines also had iridescent feathers and, unlike most modern birds, these flashy ornaments developed before the animal was fully grown.” As this study underscores, birds were, and are, one of the most diverse and rapidly evolving groups of organisms on the planet. Among other things, feathers provide perfect examples of this quick pace of diversification. Not originally designed for flight, many experts assign their appearance to that of sexual selection, something that this new study appears to agree with. It’s also thought that feathers were a way for dinosaurs (flying or grounded) to regulate their internal body temperatures. Plenty of birds use colorful feathers to attract mates, including Scarlet macaws, whose typical plumage is pictured here. Super Prin/Shutterstock The first bird-like dinosaurs appeared during the Late Jurassic, around 150 million years ago. Feathers, hollow bone structures, killing claws, and perhaps even the ability to fly – charactertistics of many modern birds – appeared in Cretaceous dinosaurs shortly afterwards. These groups include Deinonychus, quick-footed predators, and the ostrich-like oviraptorosaurs like the recently-discovered Tongtianlong. Along with the enantiornitheans, these groups died out during the mass extinction event at the end-Cretaceous around 66 million years ago – along with the likes of the terrestrial dinosaurs and the pterosaurs. Of course, other groups leading to modern birds made it through, as did their iridescent plumage. So whether the genes influencing sparkly feathers were passed down directly, or whether they evolved independently many times, it seems that certain fashion trends are essentially timeless.
  20. Pleistocene bones Florida

    These are a bunch of bones from the pleistocene period found in Florida, USA. I haven't got a clue as to what these come from so I am guessing raccoon, giant armadillo, duck, deer and maybe birds. Not sure what species but I am psyched. It would be very much be appreciated if anyone can take a look and with your pleistocene expertise maybe help me decent what bones belong to what animal.
  21. Hi I'm thinking of becoming a Paleornithologist when I'm older, I've just got a few questions for any people in this profession on here: I know the term 'paleornithologist' isn't actually a real title for a job, but something along the lines is what I mean. (Paleontologist that studies relationship between birds and dinosaurs.etc) Because I really love birds and dinosaurs and the evolutionary science behind the relationship. 1. With your work, how often do you go out an do field work/study? Eg. Capture birds and examine them? 2. How does a student studying ornithology/paleontology find themselves in a position like this? 3. How often do you get to work with theropod dinosaur fossils and paleontologists? 4. I know this is kind of a private question, and it doesn't have to be answered ; is your salary comfortable to live with? For example if you were to travel or raise a family? 5. How does an ornithologist get themselves 'higher in the ranks' when starting off? Any answers are appreciated, Thanks!
  22. Found This In My Backyard In Arizona Birds?

    Hi, I'm new here, and I am so fascinated by fossils since moving to Arizona that I decided to get some real information. I live on the edge of Arizona and Nevada. I found this under a tree in my backyard, and originally thought it was birds. But every time I move it or turn it or get closer or further away, it changes. It's driving me crazy. Please can someone tell me what this is? It is approx. 7" high and 5" wide, coral like, hard but would break easily, I hope that helps. Thanks
  23. Found this rock on Lake Michigan along the Frankfort shoreline. I thought it would be fun to experiment with some acid, so I put it in 10% or so bath for a day. I washed it off this morning and viola... little bird feet! Or, foot prints. Or maybe not. This area was a tropical, shallow sea for a long time, so maybe bird prints don't make sense. Also, other than the ID of this... I wonder how common this is? Any help would be appreciated.
  24. Here is a link to my blog 'True?' http://featherspredatebirds.blogspot.com.au It is not strictly a fossil or palaeo site. I blog about anatomy, evolution, dinosaurs, museums, fossils, geology and Australian birds. Anyway, hopefully you enjoy reading about my escapades! Susan
