‘Gap’ dino supports sudden crash
A dinosaur horn found in Montana supports the idea that dinos died after a fatal thud. The fossil turned up within a much-discussed three meters of ground below what’s called the K-T boundary marking the end of remains from dinosaur days. A supposed absence of dinosaur fossils three meters below (and older than) the boundary has been invoked in arguments that dinosaurs had died out gradually, possibly from climate change, before an asteroid walloped Earth.
