there are no yew bows in prehistoric Europe
Hmmm, carefull, I don't like to be pedantic but there is a huge difference between what you say and the statement.
"No Yew bows from that era have been discovered"
Bear in mind how few bows have survived compared with how many there doubtless were in use. Also maybe the conditions favour the survival of certain woods.
It's a miracle that any bows have survived, but one should be wary of drawing conclusions about 'all bows' based on one or two surviving bows or fragments.
Actually if I was really being pedantic I'd say the original statement doesn't actually make sense...
Do you mean:_
There 'were' no yew bows in pehistoric Europe. or
There are no prehistoric yew bows from Europe.. ?
Your tenses are confused in the original statement.
