Death of dinosaurs

Have you ever been bitten by a dinosaur? That would be something worthy of Jurassic Park. In those movies it tends to be a lethal experience. But most children will get bitten by the dinosaur bug at some point in their early years. Dinosaurs fascinate; it is the excitement of a lost world, a wild…

Hiawatha

Snow is beautiful. It turns the world white and unblemished. Children love it for play, grown-ups love it for what it hides. Soon the snow will melt again, or worse, it will age like the world ages, lose its colour and become pockmarked with dirt. The beauty is temporary, here today, gone tomorrow. What was…

This may be surprising, seeing no two rocks are the same and geologists use a never-ending series of names for these rocks, from abelsonite to zykaite. Names are what makes geology so hard.

Ghosts of Christmas past

The Jurassic Coast and the Exeter traps Our ammonite was dead, to begin with. It hadn’t always been. It was a funny place. In typical English fashion, The Old Vicarage B&B was a mix of comfort and obsolescence. The old manor house had large rooms, and was beautifully decorated. It felt like stepping centuries back…
