I like palaeoart. A while ago, I went to the ‘Dinosaurs of China’ exhibition in Nottingham and bought myself a copy of the Chinese palaeoartist, Zhao Chuang’s ‘The Age of Dinosaurs’ – a veritable picture-fest of up-to-date reconstructions of ancient beasts and plants, complete with fuzzy raptors and other bird-like therapods.

This is a new edition of the classic little guide on Blue John by Trevor Ford, who has now sadly passed away. It is published by the East Midlands Geology Society and has been revised, updated and expanded by Trevor’s colleagues, Tony Waltham and Noel Worley.

Nebraska has an excellent geological record, which is celebrated by some fine mosaics at the Nebraska State Capitol. When the building was being constructed, and at the request of Prof Hartley Burr Alexander of the Philosophy Department and from drawings by a colleague, the artist, Hildreth Meière, was asked to create a series of mosaics. These are now set out on the floor of the rotunda for all to see.

Normally, I wouldn’t be interested in semi-precious stones and other pretty things. Personally, I prefer grubbing around in the dirt, perhaps for those far more beautiful, elusive and perfectly formed Cretaceous terebratulids or Silurian trilobites. However, some semi-precious stones have the advantage of also providing a tangible link to the ancient history of life that is so fascinating.
