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 ...

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 ...

Ichnos, 2005
Since 1838, many discoveries of the tetrapod footprint taxon Chirotherium and closely similar forms have been reported from the British Middle Triassic. These have been assigned to dozens of ichnotaxa, so that the identification and interpretation of members of the ichnofamily Chirotheriidae have become confused.

Ichnos, 2005
Nine dinosaur ichnospecies from the Lower Jurassic to Upper Cretaceous of Japan, including two that are new, are described herein. The new ichnotaxa are Asianopodus pulvinicalx ichnogen. et ichnosp. nov. and Schizograllator otariensis ichnosp. nov. The Japanese ichnotaxa are allied to Lower Jurassic ichnospecies in South China, North America, Western ...

Earth-Science Reviews, 2015
Abstract The ichnofamily Siphonichnidae nov. is established for encompassing burrows of varying morphology and consisting of one or more sub-vertical tube(s) with core and surrounded mantle or lining. It includes the ichnogenera (in order of their introduction) Laevicyclus Quenstedt, 1879; Parahaentzschelinia Chamberlain, 1971; Siphonichnus ...

Zoophycos and the Role of Type Specimens in Ichnotaxonomy
, 2007 Zoophycos is a very complex trace fossil and there is still no real agreement concerning the taxonomy and the significance of the ichnofossil. What exactly are the varied structures collected under the name" Zoophycos" ? The type specimen, the first trace fossil name Zoophycos, must be found and studied in order to approach this problem from a ...

Ichnotaxonomy of bird-like footprints: an example from the Late Triassic-Early Jurassic of northwest Argentina [PDF]
Journal of Vertebrate Paleontology, 2008 The ichnotaxobases previously used to classify avian-like footprints, at the ichnogeneric, ichnospecific, and ichnofamily level, are varied and contrasting. Consequently, an agreement on the most adequate taxobases to use for classifying these vertebrate
