Rare Meteorite Type Killed Dinosaurs
Scientists have discovered that the meteorite that killed the dinosaurs was a very rare type called carbonaceous chondrites of the Ornans class.
This type of meteorite is not commonly found on Earth, which shows how unlucky the dinosaurs were.
The study used advanced nickel isotope analysis to find out the meteorite's composition.
The meteorite hit the Yucatán Peninsula in Mexico at a speed of 64,000 km/hr, causing a mass cooling that killed all life slowly.
The study does not change how we understand the dinosaur extinction but clarifies that sulphur did not play a major role in the event.

Significance of Meteorite Type
Impact of Sulphur Content
Rarity of Meteorite
Significance of Meteorite Type
The meteorite was an extremely rare type, carbonaceous chondrites of the Ornans class, indicating it traveled a great distance.
Impact of Sulphur Content
The rarity of the meteorite type does not change the understanding of the dinosaur extinction event.
Role of Sulphur
Significance of Meteorite Type
The study clarifies that sulphur did not play a major role in the mass extinction event.
Impact of Sulphur Content
The impact of the meteorite, rather than its sulphur content, was the primary cause of the mass extinction.

““Carbonaceous chondrites of the Ornans class – CO chondrites – make up a tiny fraction of that group,” he further said, adding “it really underscores how unlucky the dinosaurs were.””
