The assemblage included bones of other animals that were present in the ancient landscape alongside the mastodon.

These provide ecological context — they help characterize the environment — but do not add directly to the evidence for human activity in the way the rib specimen does.

The Manis site is important precisely because of the specificity of its key evidence.

The rib with the embedded point is exceptional.

The rest of the site’s assemblage, while potentially interesting, does not reach the same evidentiary threshold.

The strength of the Manis case rests on one rib, several fragments, and the sophisticated analysis that was eventually applied to them.
