The last dinosaur fossil discovered is a 45cm-long Browhorn which belonged to a family of plant-eating dinosaurs and scientists now believe that this ancient fossil horn reveals the creatures doom.
The fossil was found at Hell Creek Formation, South-east Montana, US, which is famous for its huge finds of many other Dinosaur fossils, but what makes this find so intriguing and so important for the experts was its very location.
The horn was unearthed just 13cm below the rock layer that marks the Cretaceous-territory boundary, (65 million years ago) which marks the fossil record where the dinosaurs died and suggests that dinosaurs did in fact live right up until the time that all traces of their existence disappeared from the planet.
What many scientists assumed in the past was that a massive asteroid smashed into the earth off the coast of Mexico at the end of the Cretaceous Period and killed off the creatures, but several sceptics argued that due a lack of dinosaur fossil evidence in the three million years leading up to the asteroid crash, that the species may have already died out before the meteor struck earth.
“This discovery gives weight to the idea that a devastating asteroid obliterated the beast.
“This discovery provides some evidence that dinosaurs did not slowly die out before the meteor struck.
“The fact that this specimen was so close to the boundary indicates that at least some of dinosaurs were doing fine right up until the impact”, said Dr Tyler Lyson, from Yale University.
