Description

Family and genus indeterminate

(Fig. 3L-Q)

MATERIAL EXAMINED AND MEASUREMENTS (IN MM). — One right dactylus, ULB-IV-A (49): L = 17; H = 6; T = 5. — One left index, ULB-IV-A (44): L = 25; H = 12; T = 7.

LOCALITY AND HORIZON. — ‘Blandinerie’ quarry, Breil (Maine-et-Loire). ‘Savignean facies’, Langhian (middle Miocene).

DESCRIPTION

Index elongate, stout, rounded in section except in the occlusal margin, which is flattened. Cuticle densely covered by rounded granules, larger in outer side. Small portion of palm appears largely concave laterally. Portion of upper margin, broad, flattened. Dactylus curved, proximally ornated with pointed granules, decreasing distally.

REMARKS

Except Paguristes gagnaisoni, no other paguroid has been reported from the Miocene sediments of the ‘Faluns’. Neither, no other paguroid species reported in the Miocene of the Mediterranean or the Central Paratethys, with which the Faluns shares great fauna affinity, shows morphological similarities with the studied dactylus and index. Comparison with recent paguroid taxa does not clarify their identity as well. The lack of a complete palm prevents us from making a generic and even familiar assignation of these remains.
