It was in fact, a very live but atypical Bird–dropping Spider Celaenia dubia.
This spider is a master of disguise, which hides all day and hunts at night without a web.
At night it suspends itself on a web strand with its claws outstretched and emits a female moth pheromone. Male moths drawn to the scent are grabbed and consumed. Here is a female spider guarding her egg sac
Check out the bent legs that enable the spider to keep them tightly against its body and the beak-like projection on the front of its carapace (top of front half) containing the slightly raised central four eyes (typical of the Orb weaver family in which it belongs) that enables it to see out when hunched up. They are no danger to humans.
