Phalanx bone Phalanx bone The phalanges (singular: "phalanx" ) are digital bones in the hands and feet of most vertebrates. In primates, the thumbs and big toes have two phalanges while the other digits have three phalanges. The phalanges are classed as long bones. The phalanges are the bones that make up the fingers of the hand and the toes of the foot. There are 56 phalanges in the human body, with fourteen on each hand and foot. Three phalanges are present on each finger and toe, with the exception of the thumb and large toe, which possess only two. The middle
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
