Northern Venezuela, where the skeletons turned up, is now bone-dry, but back then it was covered with plenty of riverside grasses for Goya to graze on. How this bucolic existence came to an end remains a mystery. One theory is that climate change killed Goya. Or, if Goya were still around 3 million years ago, when the land bridge at Panama first joined North and South America, foreign animals may have migrated south to prey on P. pattersoni, who would’ve been too big to hide and too slow to run.
