Crossed Tracks: Mesolimulus, Archaeopteryx, and the Nature of Fossils [PDF]
, 2019 Organisms leave a variety of traces in the fossil record. Among these traces, vertebrate and invertebrate paleontologists conventionally recognize a distinction between the remains of an organism’s phenotype (body fossils) and the remains of an organism ...

New Lower Devonian Polygnathids (Conodonta) from the Spanish Central Pyrenees, with comments on the early radiation of the group [PDF]
, 2014 The comprehensive study of six Pragian-lower Emsian (Lower Devonian) sections from the Spanish Central Pyrenees has yielded a rich assemblage of conodont faunas, highlighting an important succession of Polygnathus species. Among them, the presence of the

Rivista Italiana di Paleontologia e Stratigrafia, 2020 The conodont fauna of the Rotelliforme, Meeki, Occidentalis and lower Subasperum zones of Nevada (Humboldt Range) is here described. The first three zones represent, by means of the American authors, the Upper Anisian of North America, while at the base ...

Translating taxonomy into the evolution of conodont feeding ecology [PDF]
, 2016 Conodont research has long been divided between utilitarian applications to solve geological problems versus analysis of their palaeobiology. However recent advances in conodont functional analysis allow these independent stands of research to be unified,

Electron petrography of silica polymorphs associated with pseudotachylite, Vredefort structure, South Africa [PDF]
High-pressure silica polymorphs (coesite and stishovite) were described from the Vredefort structure in association with pseudotachylite veinlets. In addition to the fundamental significance of the polymorphs to genetic interpretations of the structure ...
