4. Rhinolophus cf. lemanensis
Cueva de la Fosforita.
Similarities with R. lemanensis:
 Similar sizes of M1 and M2.
 Similar termination of the postprotocrista.
 More distal development of the M1 talon than in the M2.
 Size.

 If the species is confirmed, it is the first find in the
Iberian Peninsula of this typical species from
Miocene.

5. Rhinolophus sp.
 The hypocone is absent.
 Nyctalodont with thin
labial cingulid.
 Large size.

6. Rhinopoma hardwickii Family Rhinopomatidae
The familya Rhinopomatidae is characterized by:
 Narrow development in the region of the labial
flexus and talon projection distolingually.
 Incomplete postprotocrista development.
 Longer metaconal region and flat, distally elongated
metastyle.
 Large difference between M1 and M2 in this group.

7. Rhinopoma hardwickii
 Similar size to Rh. hardwickii
 It is the first record in the
Pliocene and in the Iberian
Peninsula.
 Supports the hypothesis of Sigé
et al., 2014.

8. Myotis aff. myotis and Myotis aff. blythii Family Vespertilionidae
Genus Myotis
 Upper molars whitout talon and hypocone.
 Paraloph and metaloph may be present
 Myotodont and middle to thick labial
cingulum.
Myotodoncy
Metaconule
Both species are similars but:
1. The reduction of the m3 talonid is smaller in
Myotis blythii.
2. Myotis myotis is larger but may be overlap.

9. Myotis aff. myotis
Sites: Gilena 2 and 3
Differs from Myotis myotis
 Metaconule only in the M2.
 Some lower molars with lingual cingulid.
 Position of the hipoconulid and entoconid.

Myotis aff. blythii
Sites: Cueva de La Fosforita
Differs from Myotis blythii
 The lower molars have more developed lingual
cingulid in some than in others.
