With the "cloning" that scientists have done (most notibly, with Dolly the sheep), do you think it's feasible that they could in fact, make a dinasaur from DNA?
Not possible. There are way too many factors involved.
For starters, ribonucleic acids (i.e. DNA) are very fragile, and would certainly not survive 65+ MY of fossilization. Proteins in general are fragile molecules, easily degraded beyond the point of usefulness, which is the major problem with this technique. Most older fossils are actually just rock, with the calcium and other hard bony substances having been replaced by real rock during the process of long-term fossilization. Thus, no DNA.
The mosquito thing is interesting, but it's not possible for real, functional DNA to have survived that particular process. Also bear in mind that there are other chemical processes inside the body of a mosquito that would probably render the proteins in the dinosaur's blood useless.
Of course, the mammoths are an entirely different kettle of fish. They were frozen, which is a process that preserves protein, while causing individual cells to explode (this is the extent of my knowledge...). Thus, the chances of a mammoth being successfully cloned are quite high.
How can you PROVE some dinosaurs ate meat and killed other dino's?
Why would a herbivorous animal need powerful incisors? Also, fossils have been found of carnivorous dinosaurs with their last meals preserved in their stomachs.
