1. There is an unusually high concentration of Iridium found at the K-T boundary. Iridium loves to stick to Iron, so the Iridium that would have been on Earth originally is in the Iron core, not in the crust. Therefore, the Iridium must have been introduced by an external source; a meteorite.
2. Shocked Quartz is found at the K-T Boundary all around North America. Shocked Quartz is only produced naturally by bolide impact. Since the K-T meteorite impacted in the Mexican peninsula, it makes sense that the shocked quartz would be found only in relatively close proximity to the impact site.
3. Microtektites, which are normally found at meteorite impact sites, are found at all K-T boundary impact sites.
4. There is a massive impact crater in the Mexican peninsula.
5. In many of the K-T Boundary sections there is a fine layer of ash (disseminated Carbon) from the global wildfires that were caused.
6. There was a fern spike because other flowering plants stopped producing pollen for awhile.
7. Microdiamonds have been detected at K-T Boundary sites, but not above or below.
Through archeology they found prehistoric fossils.
That would be easy. Dinosaurs are in a group of Reptiles called Archosaurs which also includes birds,Crocodile,Alligators,Pterosaurs,and their possible ancestors- Thecodonts.
why is it important that scientists know and accept their limitations?
i dont know help
to know how is the light heavy
scientists knew that oxygen was a element as it had the atoms of only O i,e. oxygen and helped in increase in combustion
as far as I know, Yes Dinosaurs did existed
I know about dinosaurs from reading about them, watching documentaries, and a visit to a natural history museum to see dinosaur fossils in person. Scientists learned about dinosaurs by studying fossils, including bones, skin impressions, and footprints, and the rocks the fossils were found in.
I know about dinosaurs and their habitats from reading about them. Scientists learn about dinosaurs and their habitats by studying fossils.
Jesus existed, therefore dinosaurs didn't. The badlands never existed, because dinosaurs never existed, because Jesus exists.
Because they are alive today, birds are dinosaurs. And because of fossils.
Most scientists do not believe in Biblical Creation, so there is no reason to tie it with the extinction of dinosaurs. However, Creationists often say that humans originally co-existed alongside dinosaurs until the Great Flood, when dinosaurs all drowned.
Scientists don't know everything, nor do they claim to know everything.There's a lot of compelling evidence to suggest that the dinosaurs were killed of by a massive meteorite impact.
Scientists know that fish existed before amphibians because fish were found in a lower layer of rock.
Dinosaur fossils prove that they existed. I personally know about them by reading about them and watching documentaries about them.
Fossils and the fact that we were once Pangea and dinosaurs were everywhere
They found their skeletons.
There have been fossils, and skeletons from dinosaurs. Scientists don't know if they were called dinosaurs back then, but their name says almost everything about them. They are DINO, and SAURS.
