Possible Lima bean fossil

[TK46540]

Hi. Before my father passed away he gave me, what he thought was, a possible fossilized bean. He told me he had found it as a child on his aunts land near a stream bed in Indonesia back in the 1920’s. He kept it with him for years even through capture by the Japanese military and subsequent prison camp confinement. It has interesting structures and has an almost resin feel to it.  Any thoughts on this piece would be highly appreciated! Thanks guys!
