The surprising lunch of a cat-size dinosaur has been discovered in a 120 million-year-old Microraptor fossil.
As you might expect, being eaten doesn’t typically result in very well-preserved fossil remains.
All that biting and chewing, plus digestion, typically leaves few traces of a meal.
The slender digits are similar to tiny, extinct, possum-like mammals known asSinodelphysor the more mouse-likeEomaia.
However, the digits aren’t quite long enough to be either of these species.
Another outstanding question is whether Microraptor preyed on the mammal or if it merely scavenged the foot.
