( Fig. 33I, J View FIG )
DESCRIPTION
ANG M-04 is roughly oval in shape and has only two rows of cusps, with four main lingual cusps, and two main labial cusps and one posterior labial cuspule ( Fig. 33I, J View FIG ). It also possesses an incipient distal lingual ridge, with a small cuspule. All these features led us to assign this tooth to the genus Sunnyodon , a monospecific genus, S. notleyi , based on a single?P5 from the Berriasian of the Purbeck Group in England (Kielan-Jaworowska & Ensom, 1992). The Angeac-Charente tooth differs from the latter by the labial cusps that are more anteriorly located, whereas they are arranged symmetrically at the middle of the tooth length in S. notleyi , and by the absence of the anterior labial cuspule ( Fig. 33I View FIG ). This difference could be explained by the fact that these teeth belong to two different loci and/or two different species. This tooth is considered here to be a?P4 and it is referred to Sunnyodon sp. , although the validity of this genus can be debated. An upper posterior premolar of Sunnyodon has also been reported from the Berriasian strata of the Rabekke Formation on the island of Bornholm, Denmark ( Lindgren et al. 2004).
