Material. Spilia 1: one humerus ( UU SP1 1100) and one ilium ( UU SP1 1043); Spilia 3: one humerus ( UU SP3 659) and one ilium ( UU SP3 660); Spilia 4: one scapula ( UU SP4 734) and one humerus ( UU SP4 685).

Description.

Te poorly preserved scapula (UU SP4 734) from Spilia 4 shows a very slender and elongated body and a cavitas glenoidalis that is easily visible in ventral view.

Te processus glenoidalis is broken off, but the processus acromialis is rather slender and straight.

Te humeri from the Spilia localities are very small sized and slenderly built ( Fig. 24a–c View Fig ). Te diaphysis is straight and devoid of crista paraventralis. Te eminentia capitata is clearly laterally displaced compared to the main axis of the diaphysis. Te fossa cubitalis ventralis is very deep. Te cristae lateralis and medialis are moderately developed. On the dorsal surface, the olecranon scar is poorly visible.

Te small ilia from Spilia are slenderly built ( Fig. 24d– g View Fig ). Tey have no dorsal crest, but a well-developed, globular and laterally slanted dorsal tubercle is present. Te acetabulum is semicircular. Te dorsal acetabular expansion is short. Te ventral acetabular expansion is strongly anteroventrally expanded. Te lateral surface of the body of the bone is flat.

Remarks. Tese remains are here assigned to Hyla based on the following combination of characters reported as diagnostic by Bailon (1999): slender and elongated scapula with a ventrally-exposed cavitas glenoidalis and a straight processus acromialis; straight humeri devoid of crista paraventralis and provided with a laterally-displaced eminentia capitata, a deep fossa cubitalis ventralis, and a moderately-developed crista radialis; ilia with a globular and laterally-bending dorsal tubercle, an expanded ventral acetabular expansion, and without dorsal crest. All these characters fit well with the European members of the H. arborea group (Birbele et al., 2023).
