A new species for Norfolk and Cromer Forest-bed. The second record for the British Isles (after Westbury sub Mendip). Most northerly fossil record to date.
|
|
|
Notes
|
In differentiation of these remains from other large canids the following dimensions show clearly that this specimen, identified as Xenocyon differs from Canis lupus (wolf, from Barnwell Cave, Somerset or Oreston Cave, Plymouth) and Cani
s
dirus (dire wolf).
|
Note
|
JS Xenocyon lacaonoides : m1 length = 29 mm; width = 20 mm ratio = 1.45
|
Note
|
JS Xenocyon lacaonoides : M1 (carnassial) length = 28.5 mm; ration m1/m1 = 0.98
