Charadrobalaena valentinae
Taxonomy
Charadrobalaena valentinae was named by Bisconti et al. (2023). Its type specimen is MCRE 232834, a partial skeleton (partially-articulated skeleton including one jugal, two mandibular rami, cervical vertebrae fused together, nine thoracic vertebrae, a single lumbar vertebra, n), and it is a 3D body fossil. Its type locality is San Valentino Castle, which is in a Zanclean basinal (siliceous) mudstone in Italy. It is the type species of Charadrobalaena.

|---|---|---|
| M. Bisconti et al. 2023 | In addition to the differences listed above, Charadrobalaena valentinae n. gen., n. sp. differs from the other extant and fossil balaenid species in what follows: it differs from Balaena mysticetus in having a neural process protruding from the neural arc protruding dorsal transverse processes of the atlas, and a scarcely protruding anterodistal corner of the humerus; it differs from Antwerpibalaena in having all the cervical vertebrae fused in a single block and the ventrolateral portion of the cervical vertebrae protruding laterally; it differs from Eubalaena in having a well-developed olecranon process of the ulna, a straight border of the humerus, anteriorly bowed radius with unexpanded distal epiphysis, and tyrohyoid projecting posterolaterally instead of laterally; it differs from Archeobalaena, Balaenula astensis Trevisan, 1942 and Balaena montalionis Capellini, 1904 in being significantly longer and more massive (estimated total body lengths for Archaeobalaena, Balaenula astensis, Balaena montalionis and Charadrobalaena n. gen. are respectively 5.8, 6.8, 6.8 and 10.8 m with masses that were estimated respectively 1.51, 2.19, 3.09 and 10.47 t by Bisconti et al., 2021b, 2023); finally, it differs from Balaena ricei Westgate & Whitmore, 2002 in having anteroposteriorly unexpanded radius and straight proximal half of diaphysis of ulna, transversely unexpanded articular facets for occipital condyles in atlas, and a dorsally bowed neural arc of the cervical vertebrae (instead of having a triangular shape). We list two autapomorphic characters: 1) in Charadrobalaena n. gen., the anteroposterior diameters of the vertebral centra of the thoracic vertebrae posterior to T7 are longer than the corresponding dorsoventral diameters and 2) in Charadrobalaena n. gen. the teres fossa of the scapula is well marked by a crest developed obliquely from the margo caudalis to the dorsal edge of the scapula. |
