I'm going to be totally honest and tell you that there have been times when
I've been staring at diplodocid skulls and have had the heretical thought of
the possible existence of a "beaked" lip in one form or another. The most
recent occurrence of such a thought was this past July when I took an up close
and personal look at the skull of Samson after having the great fortune of
being allowed to enter Carnegie's "Paleo-Lab". After literally being nose to
nose with Samson, I walked on out into the Dinosaur Hall, took a gander at the
real diplodocus skull sitting in a case against the wall, and thought of
With the possibility of this titanosaur having good evidence pointing toward
the presence of a beak of some sort, all I can say is that my thoughts about
the occurrence of such structures, as outlined in past DML posts... well...
Let's just say this just keeps getting better and better.
Iâll have the photographs of my examination of Samsonâs skull, including
8x10s, at SVP for those of you interested.
