  3. Hi guys! I just uploaded a gallery of modern Carcharhinus upper dentitions: . The images are from my master's thesis (Smith 2015), the full text is available at (https://www.researchgate.net/publication/316735477_Species_discrimination_in_Carcharhinus_shark_teeth_using_elliptic_Fourier_analysis). Unfortunately, due to file size limitations, the images in the paper are not really good enough for detailed analysis of the morphology. So I have uploaded them individually here. I personally extracted the teeth from almost all of these jaws...If I remember correctly, they were soaked in isopropyl alcohol for several days and then the teeth removed with toothpicks and/or just pulling them out with my fingers. I cut up my fingers too many times to count trying to get these suckers out! Only the upper dentition is included; the bottom teeth in Carcharhinus are very same-y so we just focused on the uppers. Keep in mind, these represent only twelve species out of over thirty described species. They are biased towards species today present in the Western Atlantic/Gulf of Mexico. Five species now present in the Western Atlantic/Gulf of Mexico were not included due to lack of specimens/time: C. altimus, C. galapagensis, C. perezi, C. porosus, and C. signatus. Other Carcharhinus dentitions are available on the net. J-elasmo has some, I believe mostly collected from near Japan: http://naka.na.coocan.jp/JAWCarcharhinidae.html. They generally match well with my dentitions, although their Silky (C. falciformis) dentition is more coarsely serrated at the tips than mine, and the lateral notch, which is prominent in my specimens, is basically absent in the J-elasmo dentition. And of course there is Elasmo.com, a great resource for all sharks, not just Carcharhinus. Their C. falciformis dentition is similar to mine, so I don't know what's going on with J-elasmo's dentition, either it's mislabeled or Silky teeth look a lot different in the western Pacific. Or it's just an unusual specimen. And of course there are a bunch of papers online with Carcharhinus teeth, although these are generally isolated fossil teeth. The single best resource I could find for Carcharhinus identication based on teeth is unfortunately difficult to obtain, and would probably require an interlibrary loan request: Garrick, J. A. F. (1982). Sharks of the genus Carcharhinus. US Dep. Commer. NOAA Tech. Rep. NMFS Circular, 445, 194. His shark teeth images are illustrations, but well done, and with a lot of descriptive information. Purdy et al. (2001) is also a good reference:(https://www.researchgate.net/publication/284595551_The_Neogene_sharks_rays_and_bony_fishes_from_Lee_Creek_Mine_Aurora_North_Carolina). You can find references to several papers related to fossil Carcharhinus, as well as a general overview of their fossil record, in my thesis. Finally, I'm attaching a figure from my thesis, illustrating the morphological terminology used: C. falciformis, upper right jaw, 5th position from symphysis. Feel free to add additional references or information about the genus Carcharhinus. Or if anything is incorrect in this post. The subject of fossil Carcharhinus tooth identification comes up fairly regularly in the forums, so let's try and stick as much information in here as possible!

  6. So I've been reading about paleontology for awhile now, I've read all sorts of books and articles and theses, but the one thing I don't understand is what is the complete list of levels of classification? The average example usually shows eight, in this order: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species. But since this is only basic taxonomy there are more than just eight; the ones I know are: Domain, Kingdom, Phylum, Subphylum, Grandclass, Class, Subclass, Infraclass, Legion, Cohort, Grandorder, Order, Suborder, Family, Subfamily, Tribe, Genus, Species, and Subspecies; but then I remembered seeing the clade with dinosaurs and birds was shared, so where is clade in the list, and are there more classifications than I mentioned? If so, then what are they and how many do paleontologists typically actually use, and are classifications used in that order all the time, or are there some classifications that have no specific order?

  8. Scientific Name Pronunciations

    Hi all, How do you all go about pronouncing the scientific names of species that you find? So far, I've just gone with what sounds right and tweaked it based off what I hear others say. Most genus and species names are derived from Greek and Latin I believe, so looking at pronunciations in those languages may help. But is there any outside resource that you all use, or do you just say it how you see it? I'd hate to disrespect a shark by butchering his name!

  10. Can a better linguist than I (not hard!) help out here? The belemnite species suffix for Lagonibelus beaumontiana (d'Orbigny) would presumably be based on "belus" being feminine. However, original Russian sources give it as "L. beaumontianus" and other belemnite genera with the same element (Pleurobelus, Gastrobelus etc.) all have masculine species endings. I know gender endings can be tricky and -us isn't always masculine but there seems to be widespread discrepancy here. (The London NHM and Martill & Hudson's Fossils of the Oxford Clay both go with beaumontiana and we should be able to trust them to get it right...)

  12. What does it take for a species to officially be “described”? I know there must be more than just having a paper written about it, there must be some minimum requirements for the contents of the paper. And am I correct that you can’t establish a full species name unless it has been “described”?
