Final answer:
The statement that Raymond Dart coined the term "osteodontokeratic" to describe possible tool use by australopithicines is true.
Step-by-step explanation:
It is true that Raymond Dart coined the term "osteodontokeratic," meaning bone, tooth, and horn, to explain possible tool use by australopithicines. Dart was an anthropologist who proposed that early human ancestors such as australopithicines used bones, teeth, and horns as tools, which was a significant insight into the behavior of early hominids. Although Dart's original osteodontokeratic culture hypothesis, suggesting that Australopithecus africanus used bones and other organic materials as tools, is largely considered speculative today, it was an important step in understanding the potential capabilities of early hominins.
