Traditionally it has been considered to be a unit whose age has been calculated in between the Pliensbachian and Toarcian stages of the Early Jurassic, with some layers suggested to reach the Aalenian stage of the Middle Jurassic, yet modern data has found that an Early Pliensbachian to Latest Toarcian age is more possible.

Most Diplocraterion show only protrusive spreiten, like the local ones, produced under predominantly erosive conditions where the organism was constantly burrowing deeper into the substrate as sediment was eroded from the top.

Helminthopsis[10] Fodinichnia Simple, unbranched, horizontal cylinder traces Saltwater/brackish burrow-like ichnofossils.

Naktodemasis[10] Fodinichnia Straight to sinuous, unlined and unbranched burrows Freshwater/Terrestrial burrow-like ichnofossils.

Phycosiphon[10] Fodinichnia Irregularly meandering burrows Vermiform Animals Freshwater burrow-like ichnofossils.

Interpreted as dwelling structures of vermiform animals, more concretely the Domichnion of a suspension-feeding Worm or Phoronidan.

Common sedimentary features are Thalassinoides trace fossils in the fissile marlstone to claystone intervals Teichichnus[10] Fodinichnia Vertical to oblique, unbranched or branched, elongated to arcuate spreite burrow Saltwater/brackish burrow-like ichnofossils.

The overall morphology and details of the burrows, in comparison with modern analogues and neoichnological experiments, suggest Echiurans (spoon worms) or Holothurians (sea cucumbers) with a combined suspension- and deposit-feeding behaviour as potential producers.

It may be an Oniscomorpha of the order Amynilyspedida family Amynilyspedidae or a member of the order Polydesmida Plesiosauria[12][13] Indeterminate Westgrove Ironstone Member A Freshwater Plesiosaur with affinities with Pliosauridae and Neoplesiosauria Siderops[9] Siderops kehli Westgrove Ironstone Member A gigantic chigutisaurid temnospondyl, representing a relictual genus isolated in the Australian Ecoregion, as well one of the largest Mesozoic amphibians Chomotriletes[14] Affinities with the family Zygnemataceae.

A genus derived from freshwater filamentous or unicellular, uniseriate (unbranched) green algae.

"Peat moss" spores, related to genera such as Sphagnum that can store large amounts of water.

Lycopod spores, related to herbaceous to arbustive flora common in humid environments.

The lack of distinctive characters and poor conservation make this pollen difficult to classify.

Caytoniaceae are a complex group of Mesozoic fossil floras that may be related to both Peltaspermales and Ginkgoaceae.

It has been found associated with the Bennetite pollen cone Bennettistemon Araucariacites[10][14] Affinities with the family Araucariaceae in the Pinales.

Pollen that resembles that of extant genera such as the genus Actinostrobus and Austrocedrus, probably derived from dry environments.

Pollen from diverse types of Podocarpaceous conifers, that include morphotypes similar to the low arbustive Microcachrys and the medium arbustive Lepidothamnus, likely linked with Upland settings Podosporites[15][14] Affinities with the family Podocarpaceae.
