Ichnotaxonomy of the Laetoli trackways: The earliest hominin footprints

Journal of African Earth Sciences, 2011
Abstract At 3.6 Ma, the Laetoli Pliocene hominin trackways are the earliest direct evidence of hominin bipedalism. Three decades since their discovery, not only is the question of their attribution still discussed, but marked differences in interpretation concerning the footprints’ qualitative features and the inferred nature of the early hominin ...

Concerning the Erection of Ichnogenera and Ichnospecies in Vertebrate Ichnotaxonomy

Ichnos, 2002
In accord with currently accepted principles of ichnological nomenclature, ichnotaxa must be named based on morphology. An ichnotaxobase is a set of characters of a footprint or trackway that must satisfy some conditions such as coherence clarity. Quantitative measurements must be utilized in descriptive statistical studies and potentiality of typical ...

Ichnotaxonomy of microbial trace fossils in volcanic glass

Journal of the Geological Society, 2009
Abstract: Ancient microbial activity in volcanic glass creates micron-sized cavities that can be regarded as trace fossils. These are common in glassy rims of oceanic pillow lavas and volcanic breccias. Morphologically comparable mineralized traces are also found in (meta)-volcanic glasses from ophiolites and Precambrian ...

The ichnotaxonomy of vertically oriented, bivalve-generated equilibrichnia

Journal of Paleontology, 2013
Bivalves have pursued an infaunal lifestyle since early in their history. Trace fossils that have been attributed to the infaunal activity of bivalves includeHillichnus, Lockeia(=Pelecypodichnus),Lophoctenium, Protovirgularia, Ptychoplasma,SiphonichnusandScalichnus.

IV International Workshop on Ichnotaxonomy, June 21–26

Stratigraphy and Geological Correlation, 2011
The 4th International Workshop on Ichnotaxon omy took place June 21–26, 2010 at the Geological Institute RAS, Moscow, Russia. Investigation of trace fossils is a branch of sedimentary geology that is devel oping vigorously at present. The study of ichnofossils is of theoretical and practical value to paleontology, paleoecology, paleogeography ...

Damaged armour: Ichnotaxonomy and paleoparasitology of bioerosion lesions in osteoderms of Quaternary extinct armadillos

Journal of South American Earth Sciences, 2021
Abstract Osteoderms are dermal ossifications present in several vertebrates and assemble a carapace on armadillos. Here we describe ichnotaxonomically two types of bioerosion traces as well as paleopathologically ulcerative lesions on osteoderms of three specimens of Late Pleistocene Holmesina cryptae armadillos (Xenarthra, Cingulata, Pampatheriidae)

Ichnotaxonomy: A Burrow by Any Other Name…?

Short Courses in Paleontology, 1992
Ichnotaxonomy is a formal, hierarchical classification system for trace fossils (=ichnofossils, the fossilized results of behavior). It includes a binomial nomenclature similar to the zoological taxonomic hierarchy applied to organisms. A common observation from non-ichnologists is that a formal system of classification and nomenclature for footprints,

The paradoxical ichnotaxonomy of Thalassinoides paradoxicus: a name of different meanings

PalZ, 2020
Thalassinoides paradoxicus (Woodward, 1830) is a prevalent and frequently reported ichnotaxon, but given its early erection and subsequent revisions, it now is poorly understood and lumps together three different kinds of trace fossils having distinct characteristics.

The ichnotaxonomy of Conostichus and other plug-shaped ichnofossils

Canadian Journal of Earth Sciences, 1988
The systematics of the single-entrance, plug-shaped, soft-substrate trace fossils have long been in need of revision. At least 15 ichnogenera, comprising 32 ichnospecies, have been used, but an examination of the type material that is available suggests that this is excessive.
