They found tiny bones called distal phalanges, the bones at the tips of fingers and toes, from omomyoids, the ancestors of monkeys, apes, humans and tarsiers, though not the branch of primates that gave rise to lemurs, lorises and galagoes.
Another puzzle, she adds, are why the bones at the tips of the creature's digits are so long.
Ornithischians were also distinguished by an extra bone at the tip of the lower jaw called the predentary.
Cabral, however, was found to have a stress fracture of his left olecranon, a thick bone at the tip of the elbow.
The bone at the tip of the birds' wings the "hand" bone was so thick and curved, it appeared deformed.
Psittacosaurus skulls shared several adaptations with more derived ceratopsians, such as the unique rostral bone at the tip of the upper jaw, and the flared jugal (cheek) bones.
Then, after eating all the meat, you find a nub of soft bone at the tip, and you crunch it, feeling just a little illicit at having eaten something other than muscle.
As in the jaws of most ornithischians, the anterior edge of the premaxilla (a bone at the tip of the upper jaw) was toothless and probably supported a keratinous beak (rhamphotheca), although heterodontosaurids did have teeth in the posterior section of the premaxilla.
Of these cases, the radiolucency was located in Gruen zone 1 in 10 hips and in 5 hips a radiolucency was seen in Gruen zones 1 and 7. A pedestal, i.e. the formation of bone at the tip of the stem which usually closes the medullary canal was found in 18 hips.
The teeth on the premaxillae (bones at the very tip of the upper jaw) were slender, unlike those of the maxillae (the main tooth-bearing bones in the upper jaw) which had a straight posterior edge.
