Liesegang rings in Mesozoic coleoids and coprolites
“Because of physiology of coleoids, their fossils preserve soft-tissue-remains more often than other cephalopods. Sometimes, the phosphatized soft-tissues, particularly parts of the muscular mantle, display dark circular patterns. Here, we showcase that these patterns, here documented for fossil coleoids from the Jurassic of Germany and the Cretaceous of Lebanon, superficially resemble chromatophores (which enable living […]“Because of physiology of coleoids, their fossils preserve soft-tissue-remains more often than other cephalopods.

Palaeozoic stromatoporoids and chaetetids
“Palaeozoic hypercalcified sponges were ubiquitous Ordovician—Devonian reef builders but, despite their rich fossil record, their original skeletal mineralogy and microstructure remain poorly understood. This study provides the first application of electron backscatter diffraction (EBSD) to analyse skeletal structure of Silurian and Devonian stromatoporoids. The two Silurian and two Devonian stromatoporoid taxa selected are typical of […]“Palaeozoic hypercalcified sponges were ubiquitous Ordovician—Devonian reef builders but, despite their rich fossil record, their original skeletal mineralogy and microstructure remain poorly understood.

Brackish water algal reefs
“Brackish-water carbonates are far less studied than their marine or limnic counterparts.However, their association with few, specialized species enables the documentation offine-scale changes in the depositional environment. The Cenozoic Mainz Basin (Germany) was only sporadically connected to the North Sea and the Paratethys, expos-ing several transitions from marine to fresh water influence. Focusing on one […]“Brackish-water carbonates are far less studied than their marine or limnic counterparts.However, their association with few, specialized species enables the documentation offine-scale changes in the depositional environment.

Environmental drivers of body size evolution in crocodile-line archosaurs
“Ever since Darwin, biologists have debated the relative roles of external and internal drivers of large-scale evolution. The distributions and ecology of living crocodilians are controlled by environmental factors such as temperature. Crocodilians have a rich history, including amphibious, marine and terrestrial forms spanning the past 247 Myr. It is uncertain whether their evolution has been […]“Ever since Darwin, biologists have debated the relative roles of external and internal drivers of large-scale evolution.

Reconstructing Depositional Rates
“Variations in depositional rates affect the temporal depositional resolutions of proxies used for paleoenvironmental reconstructions; for example, condensation can make reconstructed environmental changes appear very abrupt. This is commonly addressed by transforming proxy data using age models, but this approach is limited to situations where numerical ages are available or can be reliably inferred by […]“Variations in depositional rates affect the temporal depositional resolutions of proxies used for paleoenvironmental reconstructions; for example, condensation can make reconstructed environmental changes appear very abrupt.

New species of Adeonellopsis
“Seven new species of Adeonellopsis MacGillivray, 1886 are described: Adeonellopsis macewindui, A. gracilis (endemic to New Zealand), A. gemina (New Zealand and Norfolk Island shelf), A. tasmanensis (Norfolk Island shelf and Gascoyne Seamount), A. periculosa Norfolk Island shelf) and A. wassi and A. minor (New South Wales shelf). All have flattened staghorn branches, which range […]
