A couple years ago, scientists announced that dinosaurs were in decline before a meteor hit the earth and killed them. Now, there’s a new theory that it was poisonous flowers and plant that weakened the great lizards.
According to recent study published in the journal Ideas in Ecology and Evolution, the emergence of the first flowering plants happens in the fossil record before the meteor strike. So, scientists are hypothesizing that dinosaurs hadn’t evolved to avoid eating the poisonous plants and ate them to their detriment.
University of Albany professor, evolutionary psychologist and co-author Gordon Gallup and his former student Michael J. Frederick found that two descendants of dinosaurs treat poisonous plants very differently: birds know to avoid poisonous plants but crocodilians keep eating them.
