Sauropod Trackway Morphometrics: An Exploratory Study Using Highway A16 Excavation at the Courtedoux-Tchâfouè Track Site (Late Jurassic, NW Switzerland)

Frontiers in Earth Science, 2022
Ichnogeneric classification of sauropod trackways is determined using qualitative and quantitative descriptions of morphological parameters. More recently, the validity of several of these parameters has been called into question (e.g., trackway gauge ...

Ichnotaxonomy as a science

Annales Societatis Geologorum Poloniae, 2018
If ichnotaxonomy is to be scientific, then its results must be repeatable. While some ichnotaxa are identified consistently, others are not, suggesting that ichnotaxonomy is not a mature science. When researchers disagree on the identification of a specimen, it suggests that closer examination is needed: an intermediate stage in the scientific method ...

ICHNOLOGICAL STUDY OF SHALLOW MARINE ENDOLITHIC SPONGES FROM THE ITALIAN COAST

Rivista Italiana di Paleontologia e Stratigrafia, 2018
Living boring sponges belonging to eight species of the genera Siphonodictyon, Cliona and Cliothosa, were collected from the limestone seafloor of the Apulian coast. Samples were taken in zero to -20 m water depth.

Lower Cretaceous sauropod trackways from Lishui City and an overview of dinosaur dominated track assemblages from Zhejiang Province, China

Journal of Palaeogeography, 2018
A relatively small number of tetrapod tracksites from Zhejiang Province fills out the fossil record from that region, which is also known to have yielded both saurischian (titanosauriform, coelurosaur) and ornithischian (basal ornithopod, ankylosaurian ...

TAXONOMIC REVIEW OF CHONDRITES AFFINIS (STERNBERG, 1833) FROM CRETACEOUS-NEOGENE OFFSHORE-DEEP-SEA TETHYAN SEDIMENTS AND RECOMMENDATION FOR ITS FURTHER USE

Rivista Italiana di Paleontologia e Stratigrafia, 2012
The branched trace fossil Chondrites affinis (Sternberg, 1833), synonymised so far with C. targionii (Brongniart, 1828), has been analyzed in an exceptionally well preserved specimen from the Saraceno Formation (?Upper Cretaceous; ?Eocene-Miocene) in the
