These three bones were found yesterday at the Stainsby beck lake deposits, I  believe the Tibia belonged to a huge Cervus Elephus, the bos skull was found close by and only two metres away from important human bone's and artifacts, as well as an identical bos skull i found last year.
 3 - Rear of the Bos skull, note the condition, i only ever wash and dry the fossils i excavate or find in the beck bed.
 4 - Note the shape and muscle attatchments, there are obviouse differences when compared to a Bos tibia.
 5 - The tibia would have measured between 40 and 45 cm, it matches a shire horse tibia i have in length.
