integument

Similar to a hypodermic needle, a nematode uses its stylet to pierce cells and pull out food -- in this case from the pseudoscorpion's hypodermis, part of the outer covering known as the integument.

They called the outer coat a cupule and proposed that it was the precursor to the outer coat, or integument, of angiosperm seeds.

To get multiple specimens of a synapsid with integument is a big deal.

To grow old, though, is not only a chronological fact but also an inevitability of fading powers and sagging integument.

And in each case, the only integument known from these dinosaurs were blotches of scaly skin from areas of the neck, hips, and tail.
