Short answer: no.
I believe that if you sort your observations by “recently updated”, the observations affected by the deletion should be at the front of the list. (“Recently updated” can be found on the advanced filters on the “identify” module; make sure to click the button to include “reviewed”, since your own observations are reviewed by default),
Deleted IDs are gone; there is no way to see what the IDs were.
