Few fossil vertebrae of this species was found in Thessaloniki , Greece.It reached a total length of 3-4 m (10-13 ft), making this perhaps the largest venomous snake discovered yet. Originally described by Sir Richard Owen, the original fossils had been lost, until rediscovery of a single vertebra was discovered somewhere near Thessaloniki in 2014.
