Morphology

sutural + bone

The compound is directly compositional: 'sutural' (relating to a suture or seam in the skull) + 'bone' yields a bone located in a suture. Although 'sutural' is technical vocabulary, the adjective+noun structure and the locative meaning are predictable, so a learner who knows the constituents can infer the intended sense.

Etymology

Sutural bone comes from suture, a word for the 'seam' where the skull bones meet, and bone, meaning the small hard part that can sit in that seam, so it refers to a tiny, odd-shaped bone found inside those joins.
