Ask a Geologist Live!

As per tradition for Earth Science Week 2015 we hosted #askageologist sessions every day. Five brilliant scientists answered your questions live on twitter.
The Ask a Geologist 2015 schedule:
Monday 12 October - Jon Tennant
3pm - 4pm : Dinosaurs, evolution and extinction
Kicking things off for us, palaeontologist Jon Tennant (@protohedgehog) will be taking questions on dinosaurs, evolution and the history of life on Earth.
Jon is also a science communicator and has a strong interest in open access publishing, so if you have questions on either of those topics, he’d be happy to answer them.
