Metacarpal bones Metacarpal bones In human anatomy, the metacarpal bones or metacarpus, form the intermediate part of the skeletal hand located between the phalanges of the fingers and the carpal bones of the wrist which forms the connection to the forearm. The metacarpal bones are equivalent to the metatarsal bones in the foot. The metacarpals form a transverse arch to which the rigid row of distal carpal bones are fixed. The peripheral metacarpals (those of the thumb and little finger) form the sides of the cup of the palmar gutter and as they are brought together they deepen this concavity. The index
Anomocephalus mm. The pes showed five partial digits and they were all robust with arthrodial joints between the distal metatarsals and proximal phalanges as well as between the phalanges. Additionally, 15 left and three right gastralia were preserved as long, thin, and delicate bones. "Anomocephalus" exhibits palatal teeth and the morphology of the teeth is consistent with a high-fiber herbivorous diet. Cisneros and colleagues suggested that "Anomocephalus" had an incipient propaliny during the occlusions due to the longitudinal dimensions of each facet of the quadrate being twice as large as the transversal dimension. They suggest that this would allow for forward
