 Including stratigraphic data. How did he determine
that AMNH 5895 was 61-67m below the K-T boundary in
the Hell Creek? Coombs was unable to find precise
stratigraphic data in AMNH archives for any of the A.
magniventris specimens. I once suggested onlist that
someone relocate the AMNH 5895 quarry to find out.
