Not all the dinosaurs in the movie are from the Cretaceous, though you're right that many of them are. Dinosaurs like dilophosaurus, stegosaurus, compsognathus, brachiosaurus are others are representatives of the Jurassic period. You mention Albertosaurs. There were not from the Jurassic period, they lived in the late Cretaceous period.Oddball;530358; said:Utahraptor is the pack hunting dinosaur featured in Jurassic Park movies. Now, before you all start pointing out that this dino is from the cretaceous instead of the jurassic, here's a tidbit for you. The books and movies were called Jurassic Park because the name Jurassic presented better than the word Cretaceous. The dinosaurs in the movie were, in fact, from the Cretaceous period. Jurassic dinosaurs were smaller (Albertosaurs were 28ft precursors to the 40ft T-Rex) than the true monsters of the Cretaceous period.
At any rate, very impressive collection!! As you can tell I am also a dinosaur fan, I would have to say that paleontology is probably my second love after fish and I have been interested in it far longer then I have fishes. I have a couple dinosaur egg fragments but nothing like what you have. One is from a saltasaurus and the other from another sauropod, I don't know what speices exactly.
