Tutankhamun's twins update A couple of messages just came over the EEF lists regarding the apparent differing ages of the two fetuses. I wondered here how one could be estimated at 5 months and the other 7-9 months if they were twins. A couple of readers there suggested that the younger one could have been a miscarriage while the other was brought to near or full term. I don't know how common this is, but it seems reasonable.
