  1. could this be a bone?

    Hi, All. I came across this yesterday, but couldn't make heads nor tails of it.... I want to think it's not a bone - one side is very smooth, while the other has a tone of small stones attached to it - but the view of the inside has me wondering.... Thanks for looking at it, and telling me what I'm looking at. I seem to have a really long learning curve! Rob @LordTrilobite @Bone guy @Haravex @Troodon
  2. Extinct species of bird came back from the dead, scientists find

    Wiped out 135000 years ago... That is some feat of magic.!!! @Auspex Any one have fossils of this bird? https://www.cnn.com/2019/05/10/africa/white-throated-rail-extinction-scli-intl-scn/index.html
  3. Hi, All. Okay - I'm trying to learn here, so please bear with me! I've been told that many of the teeth I've acquired here in Niger have been croc teeth, and that one of the ways to tell a croc tooth is by a circular base (basil?), while spinosauridae teeth are more oval.... That said, I offer the following two teeth for your informed evaluation! The bigger one is relatively narrow (the side shot with the enamel curving over the top gives you an idea), with the smaller one has a distinct "ridge" on each front/back (I know those aren't the technical terms - sorry!). As always, I greatly appreciate the education that you folks are giving me - thank you! Rob @Troodon @Haravex @jpc @LordTrilobite

  5. get your teeth into this,part three

    fish Marc Michaut:Neoselachii du Maastrichtian au sud du Niger HAL Id: hal-01729203 https://hal.archives-ouvertes.fr/hal-01729203 Submitted on 12 Mar 2018 RECOMMENDED NOTA BENE: IN FRENCH
  6. Hi, All. Here's another "large" fossil I've acquired. Same origin as the others - Agadez area of the Sahara desert in Niger. Based on the feedback I got on an earlier submission, I'm wondering if this could be from a sauropod and, if so, what part of the skeleton? As you can see, there's a lot of mud on it that I haven't tried to remove yet, as I am a complete neophyte and don't know the proper way to do so. I welcome any and all guidance on that too. Thanks so much for all your replies! Rob @Haravex @LordTrilobite @jpc @Troodon @-Andy-
  7. Hi, Folks. Thank you so much for the feedback on my first posting of teeth! Apparently there were more than a few crocodiles in the Agadez area of Niger, back when it wasn't desert! I'll post the next set, and follow that up with a posting of another very large fossil from the same area. I truly appreciate the education I'm getting on here! Rob @Troodon @LordTrilobite @jpc @-Andy-
  8. teeth from the Sahara - Agadez, Niger

    Hi, All. I finally managed to photograph all my teeth with a scale, and am hoping for someone with a lot more knowledge than me (ie: just about anyone on this site!) to tell me what I've got. I've got them divided into 6 different sets of teeth, and tried to photograph them with a bit of logic (teeth in a row, teeth flipped over to show other side in a row, bottom of teeth displayed one at a time in order, etc.). I'm trying to learn the difference between types of teeth (crocodile vs. spinosaurus vs. m-something, etc.), so if there are any common clues, I'd really appreciate the guidance. I was told that the bottom of croc teeth are more perfectly round, while others are more oval in appearance, but that's the limit of my knowledge. I also don't know the difference between "regular" crocodile fossilized teeth, and those of the "super-croc" that has been discovered in the same region of Niger. I've also got two that I can't make heads or tails out of, that I'm hoping for clarity regarding. I guess I'll start with those.... I'll try and space my submissions out, so as not to take up too much time and space. As always, thank you so much for your help and guidance! Rob @jpc @Troodon

  17. I don't read a lot about hominid fossils but I try to keep up with general knowledge of recent finds and discussions. Sometimes, the various science magazines will publish a special issue on the subject and I try to pick up a copy. The September issue of Natural History is devoted to human origins with a few articles with even one on the ancient primates of the Paleocene and Eocene along with a reprinted column by the late Stephen J. Gould. I haven't read it yet but leafed through it (nice artwork and fossil photos in it). I had seen it that month at a local Barnes & Noble but the last copy was all bent-up like an accordion. I looked for it at another store but couldn't find it. I went back to pick up the beat-up one I had seen but it was gone. After hunting around the magazine website, I found that back issues were available so I mailed away for it ($7 including shipping). Ten days later, it arrived. In case anyone else is interested, here's the link to page with the back issue address - just scroll down to it: http://www.naturalhistorymag.com/contact.html

  19. Mini Mosasaur collection

    From the album Marine reptiles and mammals

    A little collection of assorted mosasaur fossils from 2 different places that I got when I first started collecting. 2 different types of vertebrae, one is mosasaur, and the other is a questionable claim of mosasaur, a corprolite that was claimed to be that of a mosasaur, a tooth, & 7 rib fragments. 2 ribs have predation marks, as well as the large vertebra. The large vert has a round tooth indent on the very center. The 2nd rib down has tooth scratches along the surfaces, & 3rd rib down has a round tooth indent in the center, which is probably what caused a strip across the middle to break off. There are 2 other tooth marks on that rib as well, forming a diagonal line from above left of the center indent, breaking off a piece along the top, to below right.
  20. Cretaceous crocodile; likely Dyrosaurus

    From the album Marine reptiles and mammals

    Unidentified Cretaceous crocodile species, suggested by multiple people, to appear to be a Dyrosaurus, came from the second phosphatic layer of a phosphate mine(what a shocker!)around the suburbs of Khouribga, Morocco. Original teeth, not replacements. Have gone through and cleaned up the base of some of the ones that had some sand around them.
  21. Basilosaurus molar still attached

    From the album Marine reptiles and mammals

    Basilosaurus isis molar(one side serrated, the other side smooth)still embedded in a small piece of jaw bone. sadly I don't have any information about the fossil other than it is B.isis, and was found in Egypt.
  22. Osteology of Ouranosaurus nigerensis

    This takes some time to download!!!!* 114 Mb,approximately Cite this as Bertozzo F, Dalla Vecchia FM, Fabbri M. (2017) The Venice specimen of Ouranosaurus nigeriensis (Dinosauria, Ornithopoda) PeerJ 5:e3403https://doi.org/10.7717/peerj.3403 As Taquet didn't formally describe the species, this is a significant advance in our knowledge of the species. Note: This can be called a monograph due to its length. Audience: all dinosaur lovers, but please note that this IS a "technical" paper. Pretty good depiction of pelvic parts and manus. Cladogram warning! EDIT: I don't know my exact connection speed, but don't be surprised if it takes a couple of minutes.
  23. Don't blame the internet for pareidolia; it is in your genes. A head shaped rock that had been transported many kilometers 2.5 million years ago was found in Africa found with human ancestor remains and tools. See this interesting article: https://news.artnet.com/exhibitions/first-sculpture-makapansgat-pebble-1269056 I wonder how many pounds of meat this was traded for.

    mighthavebeensaidbeforeandperhapsmoreleoquently,butthisisinFrench this being the article "Fossiles du Maroc : La relation incestueuse des scientifiques et des trafiquants" The author has fairly recently edited a many-paged volume(600+pages) on the fossil vertebrates of Morocco,which I believe might constitute a state-of-the-art book.I couldn't find a TOC online, but there's at least a chapter on placoderms by Rucklin/Clement(diacritics omitted) ->page ads fairly restrained<- related: morogeoconservaPlan cours André CHARRIERE.pdf the conclusion("a"conclusion?): "Bilan : patrimoine paléontologique d’intérêt mondial ; essentiel des grands bouleversements paléoenvironnementaux, paléoclimatiques et tectoniques mondiaux sont enregistrés dans le géopatrimoine marocain." freely paraphrased: Moroccan geoheritage sites contain a wealth of information on paleoclimate,tectonics,and paleoecology
