Microfossil Christmas cards

These beautiful arrangements of microfossils were sent as Christmas cards by Arthur Earland (1866-1958) to his collaborator Edward Heron-Allen (1861-1943), both working at what was then the British Museum of Natural History.

All images were kindly provided by London's Natural History Museum, with captions supplied by the museum's microfossil curator, Dr Giles Miller. To read more about Earland and Heron-Allen, their Christmas cards and their sudden falling out, click here.
