after it drifted out to sea because if the damage had occurred beforehand, it likely would have punctured the body, preventing the buildup of bloating gases that allowed the carcass to drift out to sea in the first place. The depressions are the wrong shape to have been gastropod or sponge borings, so they are probably bite marks. However, none of the teeth belonging to the fishes preserved in the
Matanuska Formation fit the size or arrangement of the bite marks. Pasch and May therefore ruled them out as candidates for the bite marks' origin.
1447:. The distribution of bite marks corresponds inversely to the presence of flesh in the animal. For instance, lower limb bones sustained the most damage because there was the least amount of flesh shielding the bones at those locations. The largest parts of the animal would have been too large for the scavenging mosasaur to completely wrap its jaws around, and these are the areas around which the concretions formed. By contrast, the bones pulled free from the carcass were buried in the mud, which later lithified as mudstone.

present, the head must have fallen off before the carcass sank to the seafloor. The associated heteromorphic ammonites and inoceramid bivalves indicate that the
Talkeetna Mountains Hadrosaur was buried at a depth greater than 35 m. The body came to rest on its left side with limbs outstretched. Pyrite was present in the rocks around the specimen, and may have formed from

120:. Fossils of nonmarine plants are found in some beds. Fossils of two dinosaurs have been recovered from marine mudstones in the formation. The lower Matanuska Formation (MF) is several hundred meters thick and includes nonmarine and marine sediments. Campanian-Maastrichtian graded sandstone, conglomerate, and mudstone comprise the upper 2000 m of the Formation.

About 20% of the hadrosaur's bones were enveloped by calcareous concretions but every single bone not found in a concretion bore many closely spaced ovular conical depressions. These ranged in diameter from 2.1 to 5.8 mm and from 1.6 to 3.6 mm deep. The damage to the body must have occurred

Their examination of the specimen found the "Talkeetna
Mountains Hadrosaur" to be a juvenile animal about 3 m (10 feet) long. It preserves the bones of the forelimbs, part of the front feet, ribs, and tail vertebrae. Other remains probably include the back vertebrae and pelvis. The researchers could

Pasch and May also attempted to reconstruct how the
Talkeetna Mountains Hadrosaur came to be preserved in the fossil record. They determined that the specimen formed from the remains of a hadrosaur carcass that had bloated with gasses and been washed out to sea. Since none of the skull bones were
1414:. The location of the specimen makes it significant as a biogeographic link between the hadrosaurs of North America and Asia. It was also the first associated skeleton of an individual dinosaur in Alaska.
