On the Distribution of Lower Triassic Faunas [PDF]

open access: yesThe Journal of Geology, 1912
No formation has added more in recent years to our knowledge of ancient faunal geography than the Lower Triassic. In this epoch we now know three distinct and widely distributed interregional faunal zones, which are truly bench-marks in correlation. These are in sequence upward: (i) the Meekoceras zone; (2) the Tirolites zone; (3) the Columbites zone ...

A reappraisal of the Middle Triassic chirotheriid Chirotherium ibericus Navás, 1906 (Iberian Range NE Spain), with comments on the Triassic tetrapod track biochronology of the Iberian Peninsula [PDF]

open access: yesPeerJ, 2015
Triassic vertebrate tracks are known from the beginning of the 19th century and have a worldwide distribution. Several Triassic track ichnoassemblages and ichnotaxa have a restricted stratigraphic range and are useful in biochronology and biostratigraphy.

On the Presence of a Pustulated Temnospondyl in the Lower Triassic of Southern Brazil [PDF]

open access: yesActa Palaeontologica Polonica, 2009
The fossil record of temnospondyls in South America has been greatly expanded in the last 10 years, increasing their overall significance. They occur in Argentina, Brazil, and Uruguay, and range from the Guadalupian to the Late Triassic. The Early Triassic temnospondyl record in southern Brazil is mainly composed of fragmentary specimens, usually repre−
