Measurements of Antaecetus aithai vertebrae in the Faculté des Sciences Ain Chock [FSAC], Casablanca, collection.

Specimens come from two localities in southwestern Morocco, Gueran and El Breij. FSAC numbers are given where these have been assigned. Positions represented are Th, thoracic; L, lumbar; or Ca, caudal. Measurements of the centrum are length (L), anterior width (AW), anterior height (AH), posterior width (PW), and posterior height (PH), Measurements of the neural canal are width (NCW), and height (NCH). Measurements of the neural arch are centrum length anterior to the neural arch (NA1), anteroposterior length of the base of the neural arch (NA2), centrum length posterior to the neural arch (NA3), and length of NA2 as a proportion of NA1+NA2+NA3 (NA2P). Measurements of the transverse process are centrum length anterior to the transverse process (TP1), anteroposterior length of the base of the transverse process (TP2), centrum length posterior to the transverse process (TP3), and length of TP2 as a proportion of TP1+TP2+tP3 (TP2P). Numbers in square brackets are interpolated. (XLSX)
