A miniscule optimized visual system in the Lower Cambrian
Simultaneously with the development of animal body plans, probably before the Precambrian, there was an explosive diversification of visual systems. Competition of performance in these visual systemsExpand
Exceptional preservation of eye structure in arthropod visual predators from the Middle Jurassic
TLDR
Combined information about its eyes, internal organs and gut contents obtained by X-ray microtomography lead to the conclusion that this thylacocephalan arthropod was a visual hunter probably adapted to illuminated environments, thus contradicting the hypothesis that La Voulte was a deep-water environment.

Artificial compound eye: a survey of the state-of-the-art
TLDR
A comprehensive survey of the state-of-the-art work on artificial compound eyes including their system design, theoretical development and applications, and the most promising future research developments are highlighted. Expand
Telltale eyes: the lateral visual systems of Rhenish Lower Devonian eurypterids (Arthropoda, Chelicerata) and their palaeobiological implications
TLDR
The inferred lifestyles of adult individuals of these three, co-occurring Rhenish eurypterids indicate niche differentiation avoiding to some degree the competition for food in their marginal marine to delta plain transitional habitats. Expand
EXCEPTIONALLY WELL-PRESERVED ISOLATED EYES FROM CAMBRIAN 'ORSTEN' FOSSIL ASSEMBLAGES OF SWEDEN
TLDR
Six tiny, isolated, three-dimensionally preserved compound eyes are described from 'Orsten' limestone nodules dated to the Cambrian Alum Shale Formation of Sweden, showing growth in overall size and addition of new ommatidia was noticed. Expand
The eyes of a tiny ‘Orsten’ crustacean – A compound eye at receptor level?
TLDR
The early compound eye analysed here may be interpreted as a prototype representing the earliest stages of the evolution of crustacean compound eyes, as typical for all visually orientated crustaceans. Expand
Light guide lenses in trilobites?
ABSTRACT Three main types of eye have been defined in trilobites; holochroal, schizochroal and the rare abathochroal. At least in holochroal and schizochroal eyes, the lenses consist of orientedExpand
Structure and function of a compound eye, more than half a billion years old
TLDR
Functional units, at a cellular level, of a compound eye from the base of the Cambrian, shows that sophisticated eyes already existed at the beginning of the fossil record of higher organisms, while the differences between the ancient system and the internal structures of a modern apposition compound eye open important insights into the evolution of vision. Expand
Discovery of some 400 million year-old sensory structures in the compound eyes of trilobites
TLDR
Using modern techniques, including μct-scanning and synchrotron radiation analysis, this work presents the discovery of the sensory cell system of compound eyes, belonging to trilobites around 400 million years old, which allows their description and analysis. Expand
