And there’s more. New research suggests that many pterosaurs of all ages met their death in a flood.
Science polishes the account of their demise with creative storytelling:
“The fossils formed about 120 million years ago when disaster struck a group of pterosaurs. The researchers speculate that when a sudden rain flooded a river, hundreds of pterosaur eggs buried in shallow sand or under a layer of leaves or grass were drowned and washed downstream, along with a number of older individuals. Quickly buried by sediment, the eggs and bones did not decay but instead were preserved as fossils.”
Science focuses on the assumption that these flying reptiles cared for their young. In a Darwinian dog-eat-dog world, parental care might not be self-evident.
