This may sound like a stupid question to the more seasoned collectors, but I've recently started buying dinosaur teeth to collect and I can't help but notice a pattern when searching through the various fossil websites. Almost all dinosaur fossils are American or Moroccan. I've seen that international fossil trade is actually illegal in some countries causing some fossils to be unobtainable realistically. Some fossils are also extremely rare as well and are valued much higher making them extremely difficult to find.. Is it really that common for dinosaur fossils to be unobtainable? I don't mean the rare ones, I mean there's absolutely NO WAY to legally purchase them. I've seen the usual suspects on almost every website. Tyrannosaurus, Spinosaurus, Triceratops, Ankylosaurus. As well as certain Raptors, Pterosaurs, and theropods here and there. There are certain popular dinosaurs I never seem to come across though. Giganotosaurus? Brachiosaurus? Suchomimus? Are these dinosaur fossils just hard to come by or are they unobtainable to the average collector? If they are available, what's the best way to obtain them?
