ungual

1 Facebook Twitter Pinterest This ungual claw from a theropod yielded structures which appear to be red blood cells.

2 The claws would have been impressive, the authors describing the ungual phalanges, or claws, on the hands as “extremely large” and robust, about 3.5cm long.

3 Fore-feet with five toes; the first much more slender than the others, and with a smaller ungual phalange and nail; the second, though the longest, also slender.

4 The branch to digit IV inserts on the base of the ungual phalanx, with one tendinous slip to the distal end of the third phalanx and another to the distal end of the fourth.

5 Inter-phalangeal Dislocation.—The second and the ungual phalanges may be displaced backwards, forwards, or to the side.

6 The tarsal bones are short, and the digits have the usual number of phalanges, the ungual or nail-bearing ones being small and rounded.

7 It is probable that in these cases the soft parts of the 3d phalanx, and especially the ungual matrix, had not been wholly destroyed.

8 Near the distal end of the proximal phalanx, the tendon passes between two thick bands of fibro-elastic tissue which insert also on the ungual phalanx.

9 The insertion is on the base of the ungual phalanx.

10 In some few cases the metatarso-phalangeal joint is affected; but no case has been seen at the base of the ungual phalanx.

11 Researchers this week described single ungual bone — essentially, the tip of one of the tiny toes on its back foot — as having a shape identical to the same bone in adult Spinosaurus.
