I want to know the answer to the following question:
In what time period did early animals share some features with marsupials?
All the background I'm provided with is that "A later eutherian, Eomaia, dated to 125 million years ago in the Early Cretaceous, possessed some features in common with the marsupials but not with the placentals, evidence that these features were present in the last common ancestor of the two groups but were later lost in the placental lineage.". Is that enough to answer the question?
Answer: yes
