  1. An archosaurian egg ?

    Hello everyone, I am a Belgian student in biology, and I love paleontology. Last week, I was walking on a slag heap near my home in the town of Marcinelle, at the coal mine called "Bois du Cazier". My attention was mainly focused on fossils of carboniferous plants (sigilaria, cordaites, calamites, etc ...). But at one point, I picked up this pretty little pebble which seemed to me to be a fossilized archosaurian egg. The slag heaps do not really respect the order of the geological layers, so it is very difficult for me to pin a year on it. I wanted to ask you if it was possible to : - confirm / deny that it is a fossilized egg - date it approximately, in view of the material that composes it (in my opinion, it should belong to the Mesozoic area, because of the colour and the fact that it was necessary to logically pass through this layer when digging, before arriving at the carboniferous veins) - identify the order, maybe the family to which he may have belonged. Please excuse-me for my bad English, Thank you in advance for your answers !
  2. Today, instead of bemoaning the paucity of marine cretaceous rocks in my state, I reframed the situation as follows: "In the Cretaceous, most of Missouri was not ocean but land, with lots of exposed limestone that dinosaurs were likely walking around on." This led me to the following question: Do we have no fossil examples of dinosaurs that fell in sinkholes / caves / paleokarst and were preserved there, perhaps discovered during quarrying of the limestone? We definitely have such examples for fossil mammals, reptiles, etc., including Pleistocene (Ocala), Pliocene (Pipe Creek Jr.), and Miocene (Gray Fossil Site)... So why not earlier? Why not dinosaurs? Surely there were paleokarst processes in action during dinosaur times. As possibly useful information, there was definitely regional hydrothermal activity here in the Mesozoic, based on the Jurassic emplacement age of southern Illinois fluorite.

  4. I use it for holding fork and knife

    For what it's worth(coz,like,what do I know,right?) this comes with a high recommendation from yours truly.. I won't even check if that's the case,but this little gem MUST be paywalled,for sure. The author does what he does best:"talkin' about dinosaurs" carrForen_theropod.pdf
  5. nobrainer

    brawali Given the stature of the authors,I expected the best. I was NOT disappointed
