Unusual occurrence of Cochlichnus in aeolian sandstones: evidence for a stiletto fly larval origin
Abstract Cochlichnus anguineus is an ichnotaxon recognized for its distinctive regular wavy morphology. It is a characteristic trace fossil typically associated with aquatic and marginal aquatic environments. However, in this study we examine its unusual occurrence in the aeolian sandstones of the Botucatu Formation (Lower Cretaceous, Paraná Basin ...

Bivalve trace fossils in an early Miocene discontinuity surface in Patagonia, Argentina: Burrowing behavior and implications for ichnotaxonomy at the firmground-hardground divide [PDF]
Ichnofossils developed in a firmground at the contact between the middle Eocene-lower Miocene continental Sarmiento Formation and the lower Miocene marine Chenque Formation, in central-eastern Patagonia, Argentina, are assigned to Gastrochaenolites ...

Formation, preservation, and interpretation of dinosaur tracks
Abstract The fossilized tracks of dinosaurs were first reported in the scientific literature in 1836, not long after Buckland's discovery of Megalosaurus. Tracks record aspects of dinosaur locomotion, diversity, and ecology. To recover this information from a track requires an understanding of the track forming process.

ABSTRACT Fossil trackways record snapshots of the lives of ancient animals. A short trackway of unwebbed tridactyl footprints from the Kaipara region of the North Island of New Zealand contributes to the growing record of fossil footprints discovered in Aotearoa.

Abstract Taphonomic studies of Cenozoic mammals are scarce. We report a study of the taphonomy of the Corralito site (Middle Pleistocene to Holocene), Córdoba Province, Argentina, which documents the last population of the South American native ungulate typotherid Mesotherium cristatum. We discovered two specimens of M.

The ctenostome bryozoan genus Terebripora is one of four extant endolithic bryozoan taxa. Many questions surrounding its phylogeny and integrity as true biological taxon persist. This study investigates the tracemaker of Terebripora ramosa (TTR), and finds no typical vesicularioid features, instead supporting a close relationship to the other ...

ICHNOTAXONOMY AND PALEOENVIRONMENTAL ANALYSIS OF TRACE FOSSILS IN THE LATE DEVONIAN CATSKILL FORMATION, NORTH-CENTRAL PENNSYLVANIA, USA [PDF]
The purpose of this thesis is to interpret the ichnotaxonomy, paleoenvironmental distribution, and paleoecological ramifications of trace fossils from the Frasnian to Famennian Catskill Formation (CF), north-central Pennsylvania, USA.
