Perhaps the most extraordinary discovery of a 
Labyrinthodont ever made was that brought to light 
by Sir Charles Lyell and Sir William Dawson when 
investigating the coal strata of Nova Scotia. A great 
hollow tree was found fossilised in the Coal Measures. 
On breaking the specimen, the bones of a little 
Labyrinthodont were found in the hollow trunk. The 
interesting bones so fortunately discovered were sent 
to Sir Richard Owen, who named the creature 
Dondrerpeton , 1 or the tree-reptile, to perpetuate its 
wonderful discoverv. 
1 Greek —dendron, tree ; erpeton , a reptile.
