The good old days. About 60 million years ago, after ocean dinosaurs went extinct, the sea was a much safer place. Marine reptiles no longer dominated, so there was lots of food around, and birds like penguins had room to evolve and grow. Eventually, penguins morphed into tall, waddling predators.
What happened after dinosaurs went extinct?
After the dinosaurs’ extinction, flowering plants dominated Earth, continuing a process that had started in the Cretaceous, and continue to do so today. But all land animals weighing over 25 kilogrammes died out. ‘What we’re left with are basically the seeds of what we have today.
What mammals took over after dinosaurs?
Despite the relief of living in a world without rapacious dinosaurs, mammals took time to expand into the wildly varied family of beasts that diversified throughout the Cenozoic, from herbivorous “thunder beasts” to saber-toothed cats to walking whales.

No! After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth. However, small mammals (including shrew-sized primates) were alive at the time of the dinosaurs.
How did life start after dinosaurs?
Plants and animals came back much faster than thought, with plants spurring mammals to diversify, the team reports today in Science. … Half the plant species died out. With the great dinosaurs gone, mammals expanded, and the new study traces that process in exquisite detail.
