Taenidium barretti Bradshaw, 1981 in the Malhada Vermelha Formation (Lower Cretaceous), Malhada Vermelha Basin, Ceará, Brazil [PDF]
Anuário do Instituto de Geociências, 2019 The invertebrate trace fossil record in the Malhada Vermelha Basin, although recognized, is quite sparse and poor from the Systematic Ichnology approach.

Sedimentology, Volume 73, Issue 6, Page 2120-2142, October 2026.ABSTRACT Early marine carbonate cements generally form in CaCO3‐supersaturated seawater at the seabed or shallow burial depths, resulting in syn‐sedimentary cemented firmgrounds and hardgrounds. The processes controlling early marine diagenesis are complex, particularly in coastal environments where geochemistry is influenced by different water sources

Sedimentology, Volume 73, Issue 6, Page 2488-2518, October 2026.ABSTRACT Previous studies have documented genetic divergence within the last few million years between northern and southern populations of terrestrial plants and animals along the Baja California peninsula, with many studies hypothesising that the divergence is due to an ancient seaway that crossed the central peninsula and created a physical barrier ...

The Jurassic of Denmark and Greenland: Sedimentology and sequence stratigraphy of paralic and shallow marine Upper Jurassic sandstones in the northern Danish Central Graben [PDF]
Geological Survey of Denmark and Greenland Bulletin, 2003 Paralic and shallow marine sandstones were deposited in the Danish Central Graben during Late Jurassic rifting when half-grabens were developed and the overall eustatic sea level rose.

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.

Two new species of Waiparaconus (Octocorallia) of the enigmatic Family Waiparaconidae
Papers in Palaeontology, Volume 12, Issue 4, July/August 2026.Abstract Waiparaconus, a Late Cretaceous to early Cenozoic fossil, was long interpreted as a pedunculate cirripede, but is now tentatively placed in the Pennatuloidea (Order Scleralcyonacea, Class Octocorallia). New material from the Snow Hill Island Formation (lower Maastrichtian) at Vega Island, Antarctica is described and specimens from the Gingin ...

ROLE OF ICHNOLOGY IN THE HISTORY OF PHOTOGRAPHY
, 2018 Vertebrate ichnology in North America has a long and distinguished history, starting with the remarkable discoveries by Edward Hitchcock of dinosaur footprints and trackways in the Connecticut River Valley. Hitchcock assembled a unique collection that is
