crest projected nearly perpendicular to the surface of the shaft. In anconal view, the proximal end is expanded. Head not flattened, very large and wide (or expanded mediolaterad). Capital groove wide but very shallow. The surface below (distad) to the head is very wide and flat. Attachment of supraspinatus being a very large, deep groove that gouges the shaft. As a result of this, the median crest is very prominent, and a well-developed ridge is characteristic in this portion of the shaft. In the proximal third, the medial side of the shaft is completely flat, and is more triangular in cross section at this point than in other eagles or hawks examined (see Appendix 1). Line of latissimus dorsi anterioris well developed, protruding posteriorly from shaft (in two specimens available to evaluate this character) at the level of the distal portion of the deltopectoral crest. Pneumatic foramen very large, its diameter much larger than the midshaft diameter. The external border of the shaft is acute distad (or below) to the bicipital crest, as a result of a compression (anteroposterior) that produce the posterolateral flat surface of the shaft at this point.

: table 1). The proximal articulation and the medial proximal half of this element is unknown in the material from the tar seeps in study (but known from other Cuban localities). In anterior view, the shaft is long and columnar where both proximal and distal ends are proportionately small. Both anterior metatarsal borders are rounded, or convex, pronounced at both sides of the well excavated anterior metatarsal groove. Outer proximal foramen very large, close in size to the distal foramen (the inner is unknown in this material), perforating the bone from anterior to posterior face. Tubercle for tibialis anticus located central and high, slightly diagonal papilla separated from the anterolateral metatarsal border by a well grooved space. Distally the shaft is flat (by an anteroposterior compression), expanded above the trochleae. Outer extensor groove short and deep above (or proximad) to the distal foramen. Trochleae proportionately small in relation with the remaining bone, flaring well distad and abruptly from shaft (more evident in trochlea metatarsi II), and almost uniform in size. Notch between trochleae metatarsorum II and III slightly thinner. Trochlea metatarsi III short (depicting a nearly squared figure), slightly bended laterally, and with a well-defined groove. The outer ring of the latter is the distalmost point of the bone, and the trochlea metatarsi IV the shortest (less distad extended). In lateral view, the shaft is slightly arched and facies subcutanea lateralis ungrooved, being variable from a nearly flat to strongly convex surface.At distal end, the trochlea metatarsi IV is short and ovoid in shape, with posterior wing rounded, poorly projected posterodistad. At the base of the former trochlea, in the posterior half of the border of the shaft, a well-marked groove is present (at this level the bone is extremely rounded anteriorly). In posterior view, the outer proximal foramen is again about the same size of the distal foramen. Posterior metatarsal groove wide, moderately excavated proximad, very shallow distad. Crista plantaris medialis much less prominent distad than crista plantaris lateralis, although the former is better defined reaching distad the proximal end of the metatarsal facet. Metatarsal facet high (proximad), greatly excavated and expanded through its length, being deeper proximad. It is oriented mediad with prominent edges, being the border (medial border of the bone) very thin and acute. At the same level, but in the outer side, a wide and well-excavated (deeper distad) groove turns laterally and reaches the base of the trochlea metatarsi IV. The trochlea metatarsi III possess a moderate sized posterior articular surface, widely grooved, and located in an excavated, neck-like base. Trochlea metatarsi IV also well grooved, having an articular surface much more proximad than in the latter, as a result of its shortness. Trochlea metatarsi II wider at its base, which is relatively flat (or poorly excavated). The wing of this trochlea is located higher (proximal) than it’s distal contour. The distal end is expanded, produced by the flat and wide base of the trochlea metatarsi II (more noticeable than in anterior view). The internal and external intertrochlear notches are wider in posterior view than in anterior view, and both excavate (well proximad) the bone at both sides of the base (or neck) of the trochlea metatarsi III. In medial view, the metatarsal facet is facing medially, and as a result of this medial bending of the metatarsal facet onto the medial border, the crista plantaris medialis is quite visible in its distal portion (because it is less posteriorly located). The medial border along the metatarsal facet is just a thin, acute, and sharp edge, not having the flat surface found in most of the members of
