Today is the 5th November, the annual British holiday of blowing things up to celebrate things not being blown up. Seeing as it is such a flashy vibrant event, I’m turning my attention to what is perceived as one of the flashiest and showiest of the dinosaurs; a star of Jurassic Park, Dilophosaurus.
With Halloween only two days away, I thought we should turn our attentions to an animal which has become synonymous with the holiday. The word ‘Halloween’ conjures up a series of distinctive shapes in our minds; a pumpkin, a ghost, the far too early Christmas tree in the shops, and the silhouette of a flying bat. But how long could it have been this way? Would a bat have been a symbol of Halloween in the Mesozoic (if dinosaurs had been capable of celebrating this autumnal festival or been dextrous enough to craft decorations to mark it)?
Everyone knows about the great extinction at the end of the dinosaur age, but it was far from smooth sailing up until then. The Mesozoic era stretches out 180 million years, during which time many different groups of animals exploded into abundance and then died away. Even without anything so dramatic as an asteroid impact much of these were still significant catastrophes. One such time is the Toarcian Oceanic Anoxic Event (T-OAE). (more…)
