I didn't give the birdpoint dimensions because I took the photos with a penny for size comparison. Most of the bird points were about as long as the diameter of a penny, so around 1/2 to 5/8 of an inch in length, and 1/8-to 1/4 of an inch in width.
And as far as being disrespectful to the deer, I don't see it that way. This was conducted as a test with scientific value. Prehistoric hunters were not shooting foam, ballistic gel or de-boned slabs of beef with bird points, which is why I chose not to test them on those materials. I think those are unrealistic and don't give accurate results. Deer are the most widespread big game animal in the country so it made sense to test them on the real thing. Archaeologists have conducted penetration tests of stone tipped spears on dead elephants to determine if Clovis points were capable of felling mammoths. I know because I've read the articles. But I've never read any literature on someone testing arrows tipped with stone birdpoints, so I decided that I'd be the one to do it. I stand behind the test and everything I wrote because I think it was important, informative, and it has archaeological value. But I appreciate your input and opinions! Keep 'em coming.....
