On impact and volcanism across the Cretaceous-Paleogene boundary
The cause of the end-Cretaceous mass extinction is vigorously debated, owing to the
occurrence of a very large bolide impact and flood basalt volcanism near the boundary …

Recent advances in heteromorph ammonoid palaeobiology
R Hoffmann, JS Slattery, I Kruta… - Biological …, 2021 - Wiley Online Library
Heteromorphs are ammonoids forming a conch with detached whorls (open coiling) or non‐
planispiral coiling. Such aberrant forms appeared convergently four times within this extinct …

Dinosaur biodiversity declined well before the asteroid impact, influenced by ecological and environmental pressures
The question why non-avian dinosaurs went extinct 66 million years ago (Ma) remains
unresolved because of the coarseness of the fossil record. A sudden extinction caused by …

Global climate change driven by soot at the K-Pg boundary as the cause of the mass extinction
The mass extinction of life 66 million years ago at the Cretaceous/Paleogene boundary,
marked by the extinctions of dinosaurs and shallow marine organisms, is important because …

Ammonite habitat revealed via isotopic composition and comparisons with co-occurring benthic and planktonic organisms
Ammonites are among the best-known fossils of the Phanerozoic, yet their habitat is poorly
understood. Three common ammonite families (Baculitidae, Scaphitidae, and …

Buoyancy control in ammonoid cephalopods refined by complex internal shell architecture
The internal architecture of chambered ammonoid conchs profoundly increased in
complexity through geologic time, but the adaptive value of these structures is disputed …

[HTML][HTML] The old and the new plankton: ecological replacement of associations of mollusc plankton and giant filter feeders after the Cretaceous?
Owing to their great diversity and abundance, ammonites and belemnites represented key
elements in Mesozoic food webs. Because of their extreme ontogenetic size increase by up …
