A New Theropod Locality at the Jurassic Recreation Red Beds, Tucson Mountains, Arizona

, 2006
Since no other record of dinosaur activity has been detected in the Recreation Red Beds, the footprint has been assigned the name of Herrerasauripus ratkevichi, meaning 'Herrerasaurus footprint' and after local paleontologist and co-discoverer Ron ...

The new archosauriform track Pachychirotherium and the stepwise acquisition of digitigrady, cursoriality and erect stance in the group between the Permian and Triassic

Palaeontology, Volume 69, Issue 5, September/October 2026.
Abstract Archosauriforms were the most successful reptiles of the Mesozoic, becoming widespread and diverse during the Triassic. Yet, little is known of their origin, although it seems clear that it was before the end‐Permian mass extinction. An additional source of information comes from the early archosauriform footprint record.

Columnanidus calitzdorpensis ichnogen. ichnosp. nov: A new Middle Pleistocene subterranean termite trace fossil from South Africa

Journal of Quaternary Science, Volume 41, Issue 6, Page 933-949, August 2026.
ABSTRACT Termites are landscape geo‐engineers whose nesting activities substantially modify the physical and chemical properties of soils. Fossilised termite nests commonly constitute the only identifiable evidence of ancient termite activity and represent valuable trace fossil archives for reconstructing past environments.

Unusual occurrence of Cochlichnus in aeolian sandstones: evidence for a stiletto fly larval origin

Papers in Palaeontology, Volume 12, Issue 3, May/June 2026.
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 ...

Formation, preservation, and interpretation of dinosaur tracks

Palaeontology, Volume 69, Issue 1, January/February 2026.
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.

A short trackway of tridactyl fossil footprints discovered in the Kaipara region of the North Island of New Zealand

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 4, Page 816-830, December 2025.
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.

Middle Pleistocene revelations: unravelling taphonomic processes in mammals including Mesotherium cristatum (Mesotheriidae, Notoungulata), Corralito Site, Córdoba Province, Argentina

Palaeontology, Volume 68, Issue 4, July/August 2025.
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.

First soft body morphological data on the tracemaker of the endolithic bryozoan trace fossil Terebripora ramosa d'Orbigny, 1842

Journal of Morphology, Volume 285, Issue 9, September 2024.
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 ...

Tetrapod ichnotaxonomy in eolian paleoenvironments (Coconino and De Chelly formations, Arizona) and late Cisuralian (Permian) sauropsid radiation

, 2019
The tetrapod footprint record of Permian eolian environments has long been underestimated because of overall poor preservation and its apparent monospecifity.
