Samples returned from the asteroid Ryugu are similar to Ivuna-type carbonaceous meteorites
Science, 2022 Carbonaceous meteorites are thought to be fragments of C-type (carbonaceous) asteroids. Samples of the C-type asteroid (162173) Ryugu were retrieved by the Hayabusa2 spacecraft.

Magnetic Recording Stability of Taenite‐Containing Meteorites
Geophysical Research Letters, 2023 Sub‐μm taenite and tetrataenite grains observed in a number of (stony‐)iron meteorite groups are promising sources of paleomagnetic records in meteorites.

Arhaeoastronomical analysis of the Levinsadovka sacrificial complex (South Russia) [PDF]
Archaeoastronomy and Ancient Technologies, 2013 The article presents the results of a study of the unique sacrifice of the Levinsadovka sacrificial complex. On it were found large accumulations of animal bones near the buildings. An analogue of this sacrificial complex in the Northern Black Sea region

Earth’s water may have been inherited from material similar to enstatite chondrite meteorites
Science, 2020 An unexpected source of Earth's water The abundances of Earth's chemical elements and their isotopic ratios can indicate which materials formed Earth. Enstatite chondrite (EC) meteorites provide a good isotopic match for many elements but are expected to

The Effect of Jupiter's Formation on the Distribution of Refractory Elements and Inclusions in Meteorites [PDF]
Astrophysical Journal Supplement Series, 2017 We present a comprehensive evolutionary model of the Sun’s protoplanetary disk, constructed to resolve the “CAI storage problem” of meteoritics. We predict the abundances of calcium-rich, aluminum-rich inclusions (CAIs) and refractory lithophile elements

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

The breakup of the L-chondrite parent body 466 Ma and its terrestrial effects – a search for a mid-Ordovician biodiversity event [PDF]
Estonian Journal of Earth Sciences, 2023 About a third of all meteorites that fall on Earth today, the stony L-chondrites, originate from a major breakup event in the asteroid belt 466 Ma, in the early Darriwilian.

Possible Ribose Synthesis in Carbonaceous Planetesimals
Life, 2022 The origin of life might be sparked by the polymerization of the first RNA molecules in Darwinian ponds during wet-dry cycles. The key life-building block ribose was found in carbonaceous chondrites.
