DNA, the instructions for how to make a living thing, are needed to clone an animal.
We only have fossils of dinosaurs, which don’t contain any DNA. The idea of getting that DNA from an insect in amber is pretty unrealistic, it doesn’t last very well even sealed away in amber.
Also, if you clone something you need another animal to carry that embryo. We cloned a sheep because we had another sheep to put it in.
We can’t yet clone Wooly Mammoth, despite possibly getting an Elephant to birth it. The DNA just isn’t viable despite being frozen and despite only being tens of thousands rather than tens of millions of years old.
