Stratigraphy
Stratigraphy comments: J2 age suggested by Townrow (1967), based on the presence of Tsugaepollenites trilobatus pollen grains "but no definite age can be given". Plumstead (1964) gave a J1 age on presence of some or all of the Carapace Nunatak genera in certain other gondwanan floras |
