Italo40 posted a topic in General Fossil Discussion
Dear members, today I want to talk about how one of the most widely known theories of the geo/palaeontological world was born. I'm referring to the the theory according to which an Asteroid Impact caused the end-Cretaceous extinction. Last weekend I have visited the exact spot where, essentialy, this theory was first developed. It is the K/Pg Boundary in the Bottaccione section in Gubbio, a medieval town that lies on the Appenine Mountains, in the heart of Italy (see the red arrow). A widely distributed rock that makes up these mountains is the pelagic limestone sequence of th -
From the album: Invertebrates and plants(& misc.)

There definitely was plenty of it, but I guess realistically, unless it became evenly spread into the atmosphere and airborne debris, this is -
