Sellacoxa
sel-ah-KOK-sah /ˌsɛləˈkɒksə/
saddle hip
- sella · Latin · saddle
- coxa · Latin · hip
The name appears to combine the Latin words "sella" (saddle) and "coxa" (hip). That would point to a saddle-shaped feature of the hip bones. I could not verify the specific feature, so this reading is tentative.
I recall the name as a published genus (type species Sellacoxa pauli), but I'm not confident about the author, year, age, locality or current taxonomic status, so I've left those fields blank rather than guess. Please check a specialist source before relying on this entry.
