An unusual grave in Broadstone Cemetery, restored by the
A. R. Wallace Memorial Fund in 2000.
It features a 7-foot (2.1 m) tall fossil tree trunk from Portland
mounted on a block of Purbeck limestone.
Alfred Russel Wallace, OM, FRS (8 January 1823 – 7 November 1913)
was a British naturalist, explorer, geographer, anthropologist and
biologist. He is best known for independently proposing a theory of
evolution of species by natural selection that prompted Charles Darwin to
publish his own theory jointly with Wallace in 1858. Wallace lived in
Old Orchard, a house he designed himself (1901), built in 1902, knocked down ,
in 1964, which stood where Wallace Road now stands.
The age of the tree is late Jurassic, about 150 million years old.
The grave is located 50 metres beyond the main gate, on the right,
very obvious.
"Dr Paul Kenrick of The Natural History Museum, London, examined a small
fragment of the fossil wood from the grave monument using a scanning
electron microscope and found that the wood has tracheids with closely
spaced pits, similar to those known from
Protocupressinoxylon purbeckensis Francis, an approximately
146 million years old conifer of the subfamily Cheirolepidiaceae,
found in the Lower Purbeck Formation (Lower Dirt Bed or Great Dirt Bed)
in the Portland/Swanage area of Dorset."
"It is known that Wallace accompanied the American Palaeontologist
Lester F. Ward on a field trip to the Isle of Portland in 1894 to collect
fossil wood (see Ward, 1896) and one of the species collected on this
trip was even named Araucarioxylon wallacei Knowlton after him.
Interestingly, several pieces of fossil wood were found in the garden of
Old Orchard after Wallace died by the Tyndale-Biscoe family, who rented
the house from Wallace's son in 1916 (the late Mrs Barbara Waterman nee
Tyndale-Biscoe pers. comm.). These fragments, although smaller, were very
similar in appearance to the fossil on Wallace's grave, so it is possible
that the trunk on the grave was collected by Wallace and that it was taken
from Old Orchard following his death."
