Drepanosaurids *Drepanosaurus,* *Megalancosaurus,* and a specimen
mentioned by Renesto in 1999 have as their longest metacarpal III, and all
others decrease in length from their successively. Similarly, they possess
phalangeal formulae of 2-2-3-3-3, so this is even more distinctive.

Little steps are often the hardest to take. We are too used to making leaps
in the face of adversity, that a simple skip is so hard to do. We should all
learn to walk soft, walk small, see the world around us rather than zoom by it.
