An unusual oxygen-deficient ichnofauna from the Vaca Muerta Formation: implications for the ichnofacies model

Lethaia, 2023
In most oxygen-deficient ancient successions, Chondrites and Zoophycos are typical and recurrent trace fossils that are the last to disappear during deoxygenation events. Here, we report an unusual case of an oxygen-deficient ichnofauna lacking Chondrites and showing scarce Zoophycos, from the Upper Jurassic-Lower Cretaceous Vaca Muerta Formation of ...

Accretion and Differentiation of Vesta and the Mesosiderite Parent Body Inferred From Ni Stable Isotope Compositions

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract We present high‐precision Ni stable isotope data for mesosiderites, eucrites, and diogenites to investigate the accretion and differentiation of asteroid 4 Vesta. Ni isotope variations in eucrites and diogenites are dominated by kinetic diffusion and chondritic contamination, rendering them unsuitable for reconstructing Vesta's primitive Ni ...
