Dinosaurier (Dinosauria), även kallade skräcködlor, är en stor grupp reptiler som tillhör gruppen härskarödlor (Archosauria) och som oftast behandlas som en överordning. Absoluta merparten av grupperna levde endast under Mesozoikum, den era som omfattar de geologiska perioderna Trias, Jura och Krita.De tidigaste dinosaurierna utvecklades för ungefär 230 miljoner år sedan Dinosaurierna levde under perioderna trias, jura och krita. Trias. För ungefär 230 miljoner år sedan dyker de allra första dinosaurierna upp. De utvecklas från en grupp kräldjur som kallas härskarödlor, Archosaurier. Ganska snabbt utvecklas många olika grupper med dinosaurier med olika anpassningar. Plateosauru The Chicxulub crater (/ ˈ tʃ iː k ʃ ʊ l uː b /; Mayan: [tʃʼikʃuluɓ]) is an impact crater buried underneath the Yucatán Peninsula in Mexico. Its center is located offshore near the town of Chicxulub, after which the crater is named. It was formed when a large asteroid or comet about 11 to 81 kilometers (6.8 to 50.3 miles) in diameter, known as the Chicxulub impactor, struck the Earth Bottom line: Researchers have discovered evidence for an ancient microbial ecosystem in a hydrothermal system beneath the huge dinosaur-killing Chicxulub impact crater Dinosaurier (LättLäst) Forskning Allt det man vet om dinosaurierna kommer från forskare som kallas för paleontologer. Det är de som till exempel gräver upp fossil (ben och spår efter utdöda djur och växter). Sedan försöker de räkna ut hur djuret såg ut och hur det levde

The upper layers of The researchers say that while the study has given us important insights into the dinosaur-dooming impact, it also helps us understand how large craters on. The Chicxulub K-Pg Impact Crater Expedition was the first time anyone had drilled into the crater from sea. It can take a lot of time to plan and raise the money for a scientific research expedition. That's why it took twenty-six years from the time scientists found the smoking gun for the dinosaur extinction until they drilled into it to study it

Ancient volcanic eruptions didn't play a role in the mass extinction that killed off the dinosaurs, a new study says, putting the blame solely back on an asteroid that slammed into Earth
On the northern coast of the Yucatan Peninsula, near the town of Chicxulub, Mexico, is a crater about 120 miles (193 kilometers) in diameter. The asteroid that created this crater was about 6 miles (10 kilometers) wide and hit the Earth 65 million years ago.
