DOI: 10.1080/08912963.2024.2320184
Abstract: ABSTRACT This investigation uses archival data (circa 1954) to elucidate new details on Australia’s first scientifically described dinosaur trackway, located at the Fireclay Caverns-Site A, Mount Morgan, Queensland. A high-resolution archival photograph reveals two additional… read more here.

DOI: 10.1080/08912963.2025.2482185
Abstract: ABSTRACT The Early Jurassic marks a critical development in archosaurian evolution, characterised by the establishment of dinosaurs in major ecological niches. We report a new large saurischian tracksite near an irrigation dam northeast of the… read more here.

DOI: 10.1111/pala.12337
Abstract: Charcoal morphometry is increasingly employed in the analysis of Quaternary sediments, but has not been applied in studies of earlier sediments. We present findings relating to charcoal morphometry and morphotypes in a Toarcian sequence, which… read more here.
