Fossils for Future: the billion-dollar case for paleontology’s digital infrastructure Open
The digital revolution has transformed paleontology through the development of open-access, community-driven databases that underpin some of the most impactful research in biodiversity, climate change, and extinction dynamics. These system…

Cephalopod body size and macroecology through deep time Open
As actively swimming predators, cephalopods have played a key role regulating and engineering marine ecosystems for more than 500 million years and continue to do so. For the first time, we portray fluctuations of cephalopod body size incl…

Identifying the Big Questions in paleontology: a community-driven project Open
Paleontology provides insights into the history of the planet, from the origins of life billions of years ago to the biotic changes of the Recent. The scope of paleontological research is as vast as it is varied, and the field is constantl…

Unique fingerprint of marine ectotherm body size change during hyperthermal crises Open
The term "Lilliput Effect" describes a substantial decrease in the average body size of fossil assemblages during major environmental perturbations in Earth history, which is reported in many paleontological studies. The limited regional, …

Biodiversity loss and the simplification of trophic webs: Lessons from cephalopods in deep time Open
Anthropogenic global change and environmental degradation lead to not only declines in biodiversity but also the simplification of trophic webs and fundamental changes in biotic interactions as taxa are removed from ecosystems. These chang…

Using paleodata to map parasite diversity throughout Holocene Open
Parasites make up a significant portion of the global biomass and are integral to the healthy functioning of modern ecosystems. Despite their importance today, past changes in parasite distribution and diversity remain largely unexplored d…

Anatomy and size of Megateuthis, the largest belemnite Open
Belemnite rostra are very abundant in Mesozoic marine deposits in many regions. Despite this abundance, soft-tissue specimens of belemnites informing about anatomy and proportions of these coleoid cephalopods are extremely rare and limited…

Fossil constraints on the origin and evolution of Platyhelminthes are surprisingly concordant with modern molecular phylogenies Open
Trace fossils preserved with fossil worm-shaped remains suggest the presence of free-living flatworms during the Ordovician at the latest and their occurrence in terrestrial environments during the Permian. The presence of hooks associated…

Putting the F into <span>FBD</span> analysis: tree constraints or morphological data? Open
The fossilized birth–death (FBD) process provides an ideal model for inferring phylogenies from both extant and fossil taxa. Using this approach, fossils are directly integrated into the tree, leading to a statistically coherent prior on d…

Analysis of specimens preserved in amber from the Cretaceous period suggests that nematodes changed their host preference towards insects with a complete metamorphosis more recently.

Exceptions to the temperature–size rule: no Lilliput Effect in end‐<span>P</span>ermian ostracods (Crustacea) from Aras Valley (northwest Iran) Open
The body size of marine ectotherms is often negatively correlated with ambient water temperature, as seen in many clades during the hyperthermal crisis of the end‐Permian mass extinction ( c . 252 Ma). However, in the case of ostracods, si…

Parasite-induced shell damage in brachiopod Porambonites (Porambonites) laticaudata from the Late Ordovician (Sandbian) of Estonia Open
A new type of shell damage has been described in Ordovician brachiopods in Porambonites (Porambonites) laticaudata. There is a pair of small pits with somewhat different outline in the shell surface at the anterior commissure of the brachi…

Morphological disparity of early ammonoids: A geometric morphometric approach to investigate conch geometry Open
Fossils of Devonian ammonoids are abundant and well-preserved in the Anti-Atlas of Morocco; as such they provide an invaluable record of regional morphological disparity changes (diversity of shapes) that characterise the first steps of am…

LITHOLOGY CONTROLS AMMONOID SIZE DISTRIBUTIONS Open
Body-size distributions of organisms across environments in space and time are a powerful source of information on ecological and evolutionary processes. However, most studies only focus on selected parameters of size distributions (e.g., …

Where traditional extinction estimates fall flat: using novel cophylogenetic methods to estimate extinction risk in platyhelminths Open
Today parasites comprise a huge proportion of living biodiversity and play a major role in shaping community structure. Given their ecological significance, parasite extinctions could result in massive cascading effects across ecosystems. …

Evolutionary Transitions of Parasites between Freshwater and Marine Environments Open
Evolutionary transitions of organisms between environments have long fascinated biologists, but attention has been focused almost exclusively on free-living organisms and challenges to achieve such transitions. This bias requires addressin…
