More Hesperopithecus Pictures

Yesterday I posted some pictures of the Hesperopithecus tooth. Here are a few more.

They were taken from
Notes On The Type Of Hesperopithecus haroldcookii Osborn – a 1923 article by William K. Gregory AND Milo Hellman.
In the article they state:

The anatomical, palaeontological, and .other evidence already
accumulated tends to show that man, Pithecanthropus, Hesperopithecus,
and the various anthropoids form a natural superfamily group, which
may now be named the Hominoidea, in contrast with the Cercopithecoidea,
or Old World monkeys.

They provide a phylogeny as well:
The position of Hesperopithecus is circled in red. Gregory would, four years later, prove that the tooth was that of a peccary

    Didja ever wonder why getting fundies to see reality is like pulling teeth? (With apolgies to Andy Rooney)
