The other specimen I illustrated is an exceptionally large entoplastron that was estimated to yield a carapace size of perhaps 1.2 meters. But since its part of the plastron, which the holotype does not preserve, it cannot be properly assigned to Drazinderetes. (4/10)

Ken Carpenter sent his picture of the Holotype distal tail of Sauropelta; matches up well with Coombs' (fixed) drawing. Still does not jive with the material on exhibit! Did KC shoot his pic before exhibit made?? Got smashed before I shot and a tail was fabricated for exhibit?

Just triangular knives down the length of its tail. Gastonia lateral caudal plates twice the size of these (E-HH) from the Holotype of Mymoorapelta. Cover these in horn and think chainsaw blade on a handle.

Amazingly, the scan of the holotype of the new species, which we dubbed Rhombophryne vaventy (vaventy is Malagasy for 'big'), revealed a beautiful pill millipede, Zoosphaerium, in its stomach.

The name "Tylosaurus" itself references the rostrum, meaning "knob-lizard," as does the name of the type species (the first one named), T. proriger: "proriger" = "prow-bearing."

Yes I'm still tooting my own horn for naming a new species - who wouldn't?!
Sharing my favorite element for from the Parocnus dominicanus holotype (MHD 237), this nearly complete pelvis. Sloth pelvii are extremely hard to find whole, so this specimen is special!
