Whereas all the identifiable tetrapod taxa from the Economy Member have long ranges that are not diagnostic at the level of age (stage) or even epoch, a sequence of members comparable to that of the Wolfville Formation occurs in the Timezgadiouine Formation of the Argana Basin in the western High Atlas of Morocco, which was deposited at a tropical palaeolatitude similar to that of the Wolfville Formation (Olsen and Et-Touhami 2008).
Correlation of columnar sections, when arranged by palaeolatitude, demonstrates the strong disparity in dominant faunal constituents between higher latitudes and the tropics during the Triassic.
It remained as a narrow strip of sea entering from the Bay of Biscay at approximately 35[degrees]N palaeolatitude, but its palaeogeography changed in response to the increasing tectonic deformation.
Interestingly, the Amurrio fish shows characters of both Rhacolepis and Pachyrhizodus, and was found in a locality situated in a rather low palaeolatitude compared to that of most Pachyrhizodus species.
The climatic history of Valdeviar, which lay at a low palaeolatitude, may be related to the change from everwet to seasonally drier conditions which characterised the Euramerican Realm in post-Carboniferous times.
Despite warm water conditions as indicated by the occurrence of corals, calcareous algae, micritic envelopes, and suggested by the subtropical palaeolatitude between 25-30[degrees]N (e.
Thecideid fauna is only recorded in a comparable stratigraphic situation (though non-conspecific with the Iberian ones) in regions of somewhat higher palaeolatitudes (South England-Normand basins), forming part of the so-called Leptoena beds or Koninckella faunas (e.
The topics of their 19 integrated studies here include the motion of the plateau in the hot-spot frame of reference, modeled palaeolatitudes for a hot spot, a lower Cretaceous planktonic foraminiferal and nannofossil biostratigraphy, evidence of partial melting below the plateau, implications of a petrology experiment on differentiation processes, submarine basaltic glasses and their implications for magmatic processes and source region compositions, and several papers on the composition and distribution of volcaniclastic rocks and other materials.

Aspects on its origin in temperate water environments within a slowly subsiding, shallow epicontinental basin located at middle palaeolatitudes were briefly summarized by Calner et al.
