RE: Microraptor also ate fish
"the relatively short spoilage time of fish carrion" doesn't seem to put
seagulls, crows, eagles, or brown bears off too badly.
But I have often wondered why Microraptor remains are so abundant in lake
sediments. Of all the behavioral scenarios suggested for Microraptor, and with
all the encumbrance it is supposed to face from the leg feathers, the aquatic
ones have always seemed the most difficult to envision.
