EXCEPTIONAL AND STRIKING 3D TRACK-DETACHED UNDERTRACK SPECIMENS FROM THE UPPER JURASSIC OF ASTURIAS (N SPAIN)

open access: yesRivista Italiana di Paleontologia e Stratigrafia
Vertebrate palaeoichnology often aims at the identification of the trackmaker by associating diagnostic features from the known taxa’s skeletal anatomy with its inferred footprint morphology, but deep penetrative tracks and/or deep, detached undertracks

Trajectory smoothness – an important criterion in ichnotaxonomy and its implications for identifying tracemakers

open access: yesJournal of Systematic Palaeontology
Trace fossils are vital for studying organism–environment interactions in deep time. However, due to uncertainties of the tracemakers, ichnotaxonomy remains independent of biological affinity and relies instead on ichnotaxobases – diagnostic features that inform on construction and function.

Redefining the Treptichnus pedum zone at the Global Boundary Stratotype Section and Point (GSSP): A critical reassessment of the Ediacaran-Cambrian boundary. [PDF]

open access: yes, 2018
The Cambrian explosion bisects the history of life, separating relatively simple pre-Cambrian life from a complex and diverse Cambrian fauna. Due to the paucity of the body-fossil record, trace fossils often offer the only available insight into these ...
