化か石せき
化石 means 'fossil' in general; 化石人類 specifically refers to fossilized human or hominid remains.
人じん類るい
人類 means 'humanity' or 'mankind'; 化石人類 narrows this to extinct human species known from fossils.

Compound of 化石 (fossil) + 人類 (humanity, mankind). The term is a straightforward calque of English 'fossil man' or 'fossil hominid'.
