Didelphodon

As it turns out, Triebold paleontology has discovered an associated skeleton of Didelphodon, and has reconstructed it, Mike Triebold will participate in the formal description of the skeleton, which is good, as I always worry about commercially collected fossils never being described.

Anyhow, so it turns out that didelphodon was most likely a semi-aquatic mollusk-eater, like an otter, this is what the skeleton seems to suggest. The skull and teeth are large and robust, for crushing, and the body seems equal parts opossum and otter.
