I mean, I can’t personally, but they might not be as far away as you might think…
Firstly, fossil mosquitoes containing ancient blood have actually been found – one from America was about 46 million years old. That’s really old, but it’s still about 20 million years too late for the dinosaurs – it’s also a bit too late to catch Titanoboa, a snake as long as a coach, but too early for Earth’s first ever bears (which were tiny, with skulls 7cm long). Pity. But whatever the blood came from, DNA doesn’t really survive that long (it’s three-quarters gone after 1,000 years) so we couldn’t clone something from it.
There are other techniques that we could explore – there’s a new way of editing genes, called crispr, so you might use it to try and add more dino-type DNA to a crocodile or something – but I think there’s something better. If you look around the school playground after break, I you might see a lot of smallish white dinosaurs soaring around, arguing over rubbish. Yes, I do mean seagulls – every bird in the world can trace its family tree back to the first feathery dinosaurs. Birds = dinosaurs 🙂
