differs from other monachines by the abrupt distal termination of the deltopectoral crest, and the presence of a reduced and distally located epicondylar...

asymmetrically. The humerus (upper arm bone) was stout and had a sharply curved deltopectoral crest. The forelimbs of istiodactylids were large, up to 4.5 times longer...

Adele Pentland and Stephen Poropat noted that while the hatchet-shaped deltopectoral crest of FSAC CP 251 is consistent with Azhdarchidae, it differs from...

a relatively narrow "waisted" mid-shaft, with a very well developed deltopectoral crest. The radius is similarly stocky with slightly expanded ends, while...

bone shaft and larger transverse ends. Its anterior end bears a large deltopectoral crest, which was on the extremities of the bone. Charles Gilmore in...

almost-right angle. The humerus is bowed towards the midline, and the deltopectoral crest on the humerus is prominently thickened. A knob is present on...

strepsirrhines based on a broader and shallower bicipital groove, a thick ridged deltopectoral crest, the tuberosity for the teres major muscle being prominent and...

has an oval outline and is large. The humerus is short, with a large deltopectoral crest. The proximal end of the femur has a width that is much greater...

directed vertically downwards instead of to the side. On the humerus, the deltopectoral crest extends for 40% of the bone's length, and terminates halfway down...

mid-line surfaces of the acromial process were slightly concave. The deltopectoral crest (to where the deltoid muscle attached) on the upper-front part...

similar to Silesaurus among archosaurs on the line leading to birds. The deltopectoral crest extends one third of the humerus' length, but its top is located...

Further towards the distal end of the bone, the shaft forms a large deltopectoral crest which extends across nearly the entirety of the shaft. The deltapectoral...

curved in Forfexopterus. In the arm, the humerus had a well-developed deltopectoral crest that was only a quarter of the shaft's length like Beipiaopterus...

australis, and Platypterygius hercynicus. The other process is the deltopectoral crest, which is about half of the shaft length in Ophthalmosaurus, and...
