Variants and Related Words

• Cotyloid (adj): An alternative form with identical meaning.
  • The fossil showed a clear cotyloid cavity.

Synonyms

• Acetabular: Pertaining to the hip socket.

Notes

• Cotyloidal is derived from the Greek , meaning "cup-shaped." It is a rare term outside of specific scientific literature. For general understanding, acetabular or the descriptive phrase "cup-shaped socket" are more frequently encountered.
