Marine invertebrate macrofauna from the upper Blenheim Subgroup and Kulnura Marine Tongue is described. The fauna is assigned to 12 genera and 13 species, including one newly recognized genus and one new species. Based on these descriptions, three zones are recognized within the Blenheim subgroup, and conclusions about basin stratigraphy and faunal diversity relative to older Permian faunas are presented.
Use Cases
- Stratigraphic correlation analysis based on described Martiniopsis zones
- Faunal diversity studies based on the described 12 genera and 13 species
- Geological mapping based on conclusions about basin equivalences and hiatuses
- Paleoenvironmental reconstruction based on descriptions of restricted marine conditions
Strengths
- Fauna is systematically described with taxonomic assignments to 12 genera and 13 species
- Includes one newly recognized genus (Pseudonucula) and one new species
- Stratigraphic framework established with three recognized zones (Martiniopsis magna, pelicanensis, havilensis)
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
