Jul 14, 2022 · The fowl clade, including ducks and land fowl like chickens, and neoaves — a clade that consists of nearly all the other birds of today, including penguins — began to rapidly diversify right around the major extinction of all other dinosaurs, 66 million years ago.

- Mammals bit back at dinosaurs. Mammals were not the meek underdogs of the Mesozoic world that they’ve often been characterized as. This past July, paleontologists described the stunning fossil of a cat-sized Cretaceous mammal, Repenomamus, seemingly biting into the ribs of Psittacosaurus, a dog-sized horned dinosaur.

The sauropodomorph dinosaur—a long-necked herbivore that walked on two legs and was distantly related to later giants like Apatosaurus—is known not only from the bones of adult animals, but also from eggs and embryos.
- A sharp-clawed dinosaur munched plants. Troodon has been a bit of a headache for paleontologists. The dinosaur, initially named from a tooth, has required many comparisons and debates over the years to understand what the animal even looked like.

The dinosaurs went extinct around 66 million years ago and with so much time having passed it is very unlikely that any dinosaur DNA would remain today. While dinosaur bones can survive for millions of years, dinosaur DNA almost certainly does not. But some scientists continue to search for it - just in case.
