older than the dinosaurs
There are granite deposits from billions of years ago (which are much older than the oldest dinosaur), there are other granite deposits which were formed in the Cenozoic Period (after all of the dinosaurs were extinct), and there are also granite deposits from the Mesozoic Period (when dinosaurs were dominant). So the answer is: It can be, but is not necessarily so.
Fossils of sharks have been found dating back to the Silurian period, more than 200 million years before the first dinosaurs.
The colecanth lived before the dinosaurs, through the dinosaur age and now every now and then people catch one. That means they are rare but still alive.
They have been found to be older than the dinosaurs and they vary in size from the head of a needle to the size of a basketball court.
The DNA of Lophiiformes, or anglerfish, was studied to determine when they evolved. It appears that they evolved about 130 to 100 million years ago. Dinosaurs had already been around for a while, but they had not died out yet.
A Turtle! They were alive just after the dinosaurs!
No. First dinosaurs are an unranked clade, not a species. Second, there are older groups of animals than dinosaurs from the past 300 million years. Archosaurs are one such group, which include dinosaurs, crocdiles and a few other, now extinct groups of reptile. Even older are anapsid reptiles, which today consist of turtle and tortoises.
The living coelacanth, Latimeria spp., can reach a total length of 2 metres.
No, dinosaurs existed before mammals. Reptiles and amphibians existed as long ago as 359.2 million years ago, while the first mammals didn't appear until 251 millions years ago.
