Lizardling

Of reptiles there was a broken skull of some lizard, long since dead, and the eggshell of a lizardling which had hatched and gone forth upon his mission into the jungle.

[...] a little nest of dirty white rubber-shelled eggs, and recognized them for the treasure of Mrs. Sceloporus occidentalis, she left them there to complete their six-weeks period of incubation, and to turn into inch-long lizardlings.

Lizardlings thus hatch out and wander off on their own without parental contact or the opportunities for learning that such contact provides.
