The first remains of the ancient camelids in the Western Europe are known from the Miocene sediments of Venta del Moro in Spain. On the territory of Ukraine this group appeared in the Early Pliocene (Pont) (Alexeeva, 1977). In the Middle Pliocene (Kimmerian regiostage) Paracamelus alexejevi Havesson, 1950 became the dominant species in the Northern Black Sea area. A big quantity of fossil material of this species comes from the Middle Pleistocene red-brown clay, filling the carstic caves in the Pontian limestone of Odessa city (Odessa Catacombs). Among them a mandible of a much smaller camelid was found. The morphological peculiarities of the latter allow us to determine it as a separate taxon of the species rank. This new species is able not only to give us more broad vision on the taxa variation in the genus Paracamelus, but also brings some important changes to the view on the developing of this genus in the Pliocene of the Northern Black Sea area. In the present papar the traditional East-European Regiostage Scheme is used. Family Camelidae Gray, 1821 Genus Paracamelus Schlosser, 1903 Paracamelus minor* Logvynenko sp. n.

The size of the mandible and teeth are small. The length of the raw P3— P4 is 30.5 mm, M1 – 30 mm. The rest measurements of the holotype are given in a table. Teeth measurements were taken on the crowns near the alveolus, the measurements of the lower jaw – on the labial side. P3 is comparatively small. It has a slightly marked back basin, that resembles more the enamel fold passing by obliquely the inner side of a tooth from the middle up to the back part of the crown foundation. Fig. 1.

Paracamelus minor – a New Camelid Species from the Middle Pliocene … 41 P4 has a groove in the fore lingual corner, which is typical for the genus Paracamelus. Protoconid is thicken, hypoconid is arch-shaped. The groove between them is deep, ends at the beginning of the back basin level. The basin between the paraconid and metaconid is deeper than that one between the metaconid and entoconid. The basin between entoconid and entostylid of an oval shape, opened in its upper part, ends on the level of the middle height of the tooth. Index of the length of P4 to the height of the lower jaw (4/10) is about 68%. On M1 the parastylid and entostylid are more developed than the mesostilid. A middle rib is clearly distinguished on the medial side. Anterior semilunation in the back part is not closed, in spite of the considerable tooth obliteration (fig. 1, c). The index of the tooth length to the height of the mandibular body below M1 is 77.5%. M2 is similar to M1, but is a little larger. Inferior side of the lower jaw is prominent, especially under the molars, whereas a me- dial side is almost direct and the anterior part below the premolars is arched laterally. One can see a gradual increasing of the mandibular body thickness indexes from P3 to M1 (40.6% below the middle of P3 and 76.8% below the middle of M2). Compar i son. According to the measurements of the lower jaw and teeth, P. minor is smaller than P. gigas Schlosser, 1903, P. praebactrianus (Orlov, 1927), P. alexejevi Havesson, 1950, P. aguirrei Morales, 1984, P. trofimovi Sharapov, 1986, and all representatives of the genus Camelus. It is nearly of the same size as P. alutensis Stefanescu, 1895. The length of the raw P3—P4 is as follows: P. minor – 30.5 mm, P. gigas 45—46 mm (Zdansky, 1926), P. alexejevi – 38—50 mm, P. alutensis 33—35 mm (Havesson, 1954), and P. trofimovi – Tab l e 1 .

M. Logvynenko 42 33 mm (Sharapov, 1986). The anterior semilunation on M1 of P. minor is closed later (in the middle of tooth level) than in all camelids listed above. As to the construction of the lower jaw and teeth, P. minor is similar to P. alexejevi from the same locality and to P. alutensis as well. P3 of P alexejevi is less reduced than that of P. minor (the indexes of the length of this tooth to the length of the raw P3—P4 are 39.7% and 32.8% respectively). The construction of P4 (closing of the back basin, the development of conids, stylids and basins) in both species is similar, but P. alutensis has a groove between protoconid and hypoconid which comes into the crown of a tooth deeper and separates the posterior part more clearly. The construction of molars in both species is similar as well, but their middle ribs in P. minor are more marked. The thickness of the jaw from P3 to M2 (in- dex 13/9—16/12) increasing quickly than in P. alexejevi. P. alutensis differs from P. minor by larger absolute and relative thickness of the lower jaw (see table), as well as by its shape and construction of M1 (Havesson, 1954, Alexeeva, 1977). P. aguirrei from the Later Pliocene of Spain is considerably larger. The length of its P3 is 20 mm. A posterior basin of P3 in this species is larger and is removed to the center of the tooth crown (Pickford, Morales, Soria, 1995). Notes . Morphological peculiarities of P. minor differ it from all earlier known species of the genus Paracamelus and shows that this camelid is related to P. alexejevi and P. alutensis. Since P. minor existed at the same time as P. alexejevi and it has many similar features with the latter, it makes possible to suppose that both species are very related and could have a common ancestor which is still unknown. Moreover, the morphology of the mandible (especially its considerable thickness) and lower teeth give a possibility to suppose that described species could be a direct ancestor of P. alutensis. Therefore, the view of V. A. Topachevsky (1956) on the origin of P. alutensis from P. alexejevi can be changed – there are much more reasons to regard P. minor as the ancestor of P. alutensis.
