CAENOMERYX CF. PROCOMMUNIS ( FILHOL, 1877)

Referred material: Mas de Got: a right maxillary fragment P3/-P4/ ( MGT 3178), five mandibular fragments, one with left P/2-M/1 ( MGT 118), one with left P/2-P/4 ( MGT 155), one with right P/2-P/3 ( MGT 3207), and one with left P/3-P/4 ( MGT 127, MGT 3206). Pech Crabit: three maxillary fragments, one with right P2/ -P3/ ( PCT 420), two with right P3/-P4/ ( PCT 350, PCT 398); seven mandibular fragments, one with right P/2- M/2 ( PCT 938), one with left P/2-M/2 ( PCT 951), one with right P/2-M/1 ( PCT 441), one with right P/2-P/4 ( PCT 486), one with left P/2-P/4 ( PCT 982), and two with left P/2-P/3 ( PCT 995, PCT 997). Itardies: three maxillary fragments, one with left P1/-M1/ ( ITD 952), one with right P1/-P2/ ( ITD 959), and one with left P1/ -P2/ ( ITD 961). Mounayne: two left maxillary fragments with P3/-P4/ ( MOU 210, MOU 211), and a left mandibular fragment P/3-P/4 ( MOU 143). Roqueprune 2: three mandibular fragments, one with right P/1-P/4 ( ROQ 2344), one with left P/3-M/2 ( ROQ 2341), and one with left P/3-P/4 ( ROQ 2383).

Measurements: See Table 5. For C. procommunis , the Kolmogorov- Smirnov and Shapiro- Wilk tests confirm normality for P/3 from Pech Crabit (N = 7, K–S, d = 0.246, P> 0.20, W = 0.905, P = 0.368).

The weakness of variation coefficients confirms the homogeneity of Caenomeryx procommunis samples from localities of the MP23 reference level. For the length of P/3 from Pech Crabit, Mounayne, Roqueprune2: N = 11, M = 4.40, s = 0.29, K–S, d = 0.19, P> 0.20, W = 0.95, P = 0.697, V = 6.54.

Description

Upper dentition: A number of maxillary fragments bear a short premolariform P1/, a P2/ with a wide
