With lots of overburden removed on Monday, we were able to focus our efforts today on getting into the bonebed. This quickly paid off, with Amanda and Laura uncovering a small baleen whale right dentary (lower jaw), shown above.
For reference, the posterior end of the bone is on the left. The anterior part is missing, and the middle is completely crushed.
We also spent a good part of the day working on the deeply weathered zone at the front of the pit. It’s very difficult to recover bones from the weathered zone, as the acidic sediment partially dissolves the bones and cements everything together. Even so, we collect what we can, and occasionally get decent material, such as a second probable dentary:
We’re also getting our usual range of teeth and small bones, including this shark vertebra that Amanda found while working on the dentary:
It’s supposed to be brutally hot the next few days, but at least there’s no rain in the forecast, so hopefully we can get a lot of work done.
