  1. New paper out today that examines the Spinosauridae family. Unfortunately the paper is mostly in Portuguese. Google translate can be very helpful. Paper: "We conclude that out of these 20 taxa six can be regarded as nomina dubia (Ostafrikasaurus crassiserratus, Suchosaurus girardi, Spinosaurus maroccanus, Siamosaurus suteethorni, Sinopliosaurus fusuiensis, Suchosaurus cultridens)due to the lack of diagnostic material and autapomorphies." https://sbpbrasil.org/publications/index.php/paleodest/article/view/357
  2. Are Mosasaurs considered lizards?
  3. Bateman, R.M. and DiMichele, W.A., Escaping the voluntary constraints of “tyre-track” taxonomy. Taxon 00 (00), pp. 1–16 Wiley PDF Yours, Paul H.
  4. What is the proper ending for the specific name of Wilkingia terminale: terminale or terminalis? Allorisma was renamed Wilkingia in 1959 by Wilson. I suspect since the genus name was changed the ending of the specific name needed to change to match the case, gender and number of the genus name. Anyone fluent in Latin and good at matching their word endings? http://fossilworks.org/bridge.pl?a=taxonInfo&taxon_no=18845 http://entomology.ifas.ufl.edu/frank/KISS/kiss9.htm
  5. 7 ft tall Three toed tracks Walks flat on its feet, not on the sides of its feet Three fingered claw marks Osteoderms in skin Ancestor of cloepus, not bradypus Found in North America (do any known ground sloths have a smaller tail or even no tail at all?)

    Question on Taxonomy

    Hi, I have looked through the internet and couldn't find information on this and thought maybe someone passing through could give me and quick answer. Why things share similar words in latin when sometimes they are not related at all. For example Dickin(Sonia) ( a flat Ediacaran animal ) Dick(Sonia) ( a tree fern ) Cook(Sonia) ( one of the first vascular plants ) These are three different species that share not too much. (aside from everything is connected) Or another example is: Archaeo(therium) ( a boar like predator in the Miocene ) Kayenta(therium) ( a semi-aquatic rodentoid from early Jurassic) Mega(therium) ( a huge land sloth from early Pliocene ) Balochi(therium) ( huge hornless rhino from oligocene) However like the Therium family above, this simply means mammal or marsupial. Sonia contains animals and plants. And unlike Therium I still have no explanation for Sonia. If anyone knows, please let me know.
