Dinosaur Die Out Was Gradual, Miserable, Painful
“Some dinosaurs definitely would have been instantly killed in the impact, those in the vicinity of the impact site for instance; others may have perished in the tsunami caused by the blast,” lead author Manabu Sakamoto of the University of Reading’s School of Biological Sciences told Discovery News.He continued, “The majority of the remaining dinosaurs all over the rest of the world would have likely starved to death as vegetation died out owing to the layer of ash that blacked out the sky (nuclear winter).”

Dinosaurs Survive!
“Not all dinosaurs died out 65 million years ago. Avian dinosaurs--in other words, birds--survived and flourished. Scientists at the American Museum of Natural History estimate that there are more than 18,000 species of birds alive today. A variety of other species also survived on land, including frogs, snakes, lizards and mammals.”

K–T extinction
“Of the dinosaurs, only the archosaurs, a lineage that gave rise to modern birds and crocodilians, survived the extinction. Of the planktonic marine flora and fauna, only about 13 percent of the coccolithophore and planktonic foraminiferal genera remained alive. Among free-swimming mollusks, the ammonoids and belemnoids became extinct.”
