Dinosaur hunting - Thursday 7th October

Don't forget this Thursday's Bath Geological Society lecture 'Cretaceous Dinosaur hunting in North Africa' to be given by Dr. David Martill from Portsmouth University.
The mid Cretaceous Kem Kem deposits of Morocco, and coeval beds elsewhere in Saharan Africa have been yielding dinosaurs for nearly a century, but little science has been done on these remarkably rich deposits. This is about to change. The sequence is dominated by fluvial sandstones, but passes upwards into lacustrine mudstones and eventually becomes a series of shallow water carbonates rich in fossil shells and small fishes. The sandstones contain bone beds of worn and eroded bone fragments, but also layers with articulated remains. Some erosion surfaces are littered with dinosaur teeth and Berber children actively seek these out to sell to passing tourists in Erfoud and Rissani. We now know of at least five different theropod dinosaurs from Morocco including the gigantic Spinosaurus (image) and Carcharadontosaurus.
This talk introduces the Kem Kem dinosaurs and the environment they lived in, and provides a taste of what it is like to hunt dinosaurs in the Sahara Desert.
The talk will be held at BRLSI, 16 Queen Square, Bath at 7.30 p.m. Everyone is welcome - visitors £4.00. Free refreshments will be served after the talk.
