There are four special features:
- the exceptional completeness of the embryonic skull; it appears
to be less damaged than any described previously.
- the exquisite preservation of fine detail, such as the claws,
revealed by chemical preparation techniques.
- the discovery of preserved soft-tissues, such as cartilage
and perhaps muscle and skin, in the therizinosaur eggs.
- the recognition of various agencies which have contributed
to the partial preservation and to the partial destruction of
the embryos.
