Early vertebrate evolution has been characterized as a gradual shift from passive to more active feeding modes. However, this evolutionary scenario is contingent on poorly constrained inferences of the feeding ecology of extinct stem-gnatho...

Studies of the origin of evolutionary novelties (novel traits, feeding modes, behaviours, ecological niches, etc.) have considered a number of taxa experimenting with new body plans, allowing them to occupy new habitats and exploit new trop...
Diversity dynamics of microfossils from the Cretaceous to the Neogene show mixed responses to events [0.03%]
从白垩纪到新近纪微化石多样性动态显示了对事件的混合响应

Microfossils have a ubiquitous and well-studied fossil record with temporally and spatially fluctuating diversity, but how this arises and how major events affect speciation and extinction is uncertain. We present one of the first applicati...
Skin patterning and internal anatomy in a fossil moonfish from the Eocene Bolca Lagerstätte illuminate the ecology of ancient reef fish communities [0.03%]
来自埃奥纪博尔卡层位的化石月鱼的皮肤图案和内部解剖结构揭示了古代珊瑚礁鱼类群落的生态状况
Valentina Rossi,Richard Unitt,Maria McNamara et al.
Valentina Rossi et al.
Colour patterning in extant animals can be used as a reliable indicator of their biology and, in extant fish, can inform on feeding strategy. Fossil fish with preserved colour patterns may thus illuminate the evolution of fish behaviour and...
Taphonomic experiments resolve controls on the preservation of melanosomes and keratinous tissues in feathers [0.03%]
埋藏学实验解析羽毛中的黑色素小体和角蛋白组织保存条件及控制因素

Tiffany S Slater et al.
Fossils are a key source of data on the evolution of feather structure and function through deep time, but their ability to resolve macroevolutionary questions is compromised by an incomplete understanding of their taphonomy. Critically, th...

A major uncertainty in estimating energy budgets and population densities of extinct animals is the carrying capacity of their ecosystems, constrained by net primary productivity (NPP) and its digestible energy content. The hypothesis that ...
Neurocranial anatomy of the petalichthyid placoderm Shearsbyaspis oepiki Young revealed by X-ray computed microtomography [0.03%]

Stem-group gnathostomes reveal the sequence of character acquisition in the origin of modern jawed vertebrates. The petalichthyids are placoderm-grade stem-group gnathostomes known from both isolated skeletal material and rarer articulated ...

Fossil taxa are critical to inferences of historical diversity and the origins of modern biodiversity, but realizing their evolutionary significance is contingent on restoring fossil species to their correct position within the tree of life...

Understanding how regional ecosystems respond to sea-level and environmental perturbations is a main challenge in palaeoecology. Here we use quantitative abundance estimates, integrated within a sequence stratigraphic and environmental fram...
