Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Nzvimbo inonzi Morrison Formation yave iri nzvimbo yakanaka yokuvhima zvisaririra. Miti yomunguva yacho yakaratidzwa nezvisaririra zvemarwizi akasvibira, fungi, mosses, horsetails, ferns, cycads, ginkgoes, uye mhuri dzinoverengeka dze conifers. Zvipembenene zvemhuka zvakawanikwa zvinosanganisira bivalves, zvipembenene, hove dzine mapapiro, matatya, salamanders, turtles, sphenodonts, lizards, terrestrial and aquatic crocodylomorphs, several species of pterosaur, numerous dinosaur species, and early mammals such as docodonts, multituberculates, symmetrodonts, uye triconodonts. MaDinosaurs anozivikanwa kubva kuna Morrison anosanganisira ma theropods Ceratosaurus, Ornitholestes, Tanycolagreus, uye Torvosaurus, ma sauropods Haplocanthosaurus, Camarasaurus, Cathetosaurus, Brachiosaurus, Suuwassea, Apatosaurus, Brontosaurus, Barosaurus, Diplodocus, Supersaurus, uye Amphicoelias, uye ma ornithischians Camptosaurus, Dryosaurus, uye Stegosaurus. Allosaurus inowanzowanikwa munzvimbo imwe chete neApatosaurus, Camarasaurus, Diplodocus, uye Stegosaurus. Zvinhu zvakagadzirwa muLate Jurassic yePortugal uko Allosaurus iripo zvinotsanangurwa kuti zvakafanana neMorrison asi zvine simba rakasimba remakungwa. Mazhinji emadinosaurs eMorrison Formation ndiwo marudzi akafanana neaya anoonekwa mumatombo ePortugal (kunyanya Allosaurus, Ceratosaurus, Torvosaurus, uye Stegosaurus), kana kuti ane shamwari yepedyo (Brachiosaurus neLusotitan, Camptosaurus uye Draconyx).Allosaurus yaigara pamwe chete nemamwe ma theropods makuru Ceratosaurus uye Torvosaurus muUnited States nePortugal. Zvitatu zvacho zvinoratidzika kuva zvaiva nenzvimbo dzakasiyana-siyana dzomuviri, zvichienderana nokuumbwa kwomuviri uye nzvimbo yezvicherwa. Ceratosaurs ne torvosaurs vangave vaifarira kuva vanoshingaira pedyo nemigwagwa yemvura, uye vaiva nemiviri yakaderera, yakatetepa iyo ingadai yakavapa mukana mumasango uye pasi pemasango, nepo allosaurs yakanga yakanyatsobatana, ine makumbo marefu, inokurumidza asi isinganyanyi kukwanisa, uye inoratidzika kunge yaifarira mafashamo akaoma. Ceratosaurus, inozivikanwa zviri nani kupfuura Torvosaurus, yakanga yakasiyana zvikuru neAllosaurus mukuumbwa kwomuviri...  Mubvunzo: Ndeipi dinosaur yaiva nemakumbo akareba kupfuura mamwe ose
