I sent this message out once, but I don't think it
got through. Here it is again;
Hello everyone,
I was doing a little research on the web last night
and found this at: http://www.aqd.nps.gov/grd/geology/paleo/nps_paleo_vol1/dino.htm
Has there been anymore information released on this
find? And I'm not for sure how old this is.
Cheers,
Todd Marshall
A NEW
CARNOSAURIAN DINOSAUR (SAURISCHIA: TETANURAE) FROM THESALT WASH MEMBER OF THE
MORRISON FORMATION (JURASSIC:KIMMERIDGIAN) OF DINOSAUR NATIONAL MONUMENT Dan Chure Dinosaur National Monument Jim Madsen DinoLab, Utah An isolated, articulated skeleton of a large (20-25 ft. long) carnivorous dinosaur is currently being excavated in Dinosaur National Monument. The specimen was discovered in 1989 during a paleontological survey of the Morrison Formation. The part exposed to date includes all of the skeleton from the should blades back to the tip of the tail. The front part of the specimen continues into the hill side and excavations are continuing. It is highly likely that all of the skeleton (including the skull) is present. Although preparation has only been done in the field at present, the specimen shows a suite of morphological features quite at variance with any other known Morrison theropod dinosaur and indicates that it is at least a new species and probably a new genus. Pelvic structure shows similarities with mid-Jurassic theropods (Piatnitzskyosaurus) from Argentina and late-Cretaceous tyrannosaurids. Overall morphology strongly suggests carnosaurian tetanuran affinities. This specimen is one of the best carnivorous dinosaur skeletons ever found anywhere in the Morrison Formation and the only good theropod skeleton from the Salt Wash Member of the Morrison. |
