Nocturnality constrains morphological and functional diversity in the eyes of reef fishes
Both teleost reef fish and terrestrial amniotes meet the functional requirements of dim-light vision with a similar evolutionary response of morphological and optical modifications, and the trade-off between improved dim- light vision and reduced optical diversity may be a key factor in explaining the lower trophic diversity of nocturnal reef teleosts.
Nocturnality in Dinosaurs Inferred from Scleral Ring and Orbit Morphology
It is shown that the eyes of Mesozoic archosaurs were adapted to all major types of diel activity (that is, nocturnal, diurnal, and cathemeral) and provide concrete evidence of temporal niche partitioning in the Mesozoics.

Its presence documents the rapid evolution of modern marine ecosystems in the Triassic where the same level of complexity as observed in today’s marine ecosystems is reached within 8 My after the Permian-Triassic mass extinction and within 4 My of the time reptiles first invaded the sea.

A NEW MIXOSAURID ICHTHYOSAUR FROM THE MIDDLE TRIASSIC OF CHINA
The holotype of Mixosaurus maotaiensis, which is very fragmentary and has no taxonomic value at the species level, is found to be undiagnostic, and hence the lately introduced, monospecific genus name for this species needs to be abandoned.
Nocturnality in synapsids predates the origin of mammals by over 100 million years

Recognizing the complexity of diel activity patterns in non-mammalian synapsids is an important step towards a more nuanced picture of the evolutionary history of behaviour in the synapsid clade.

It is shown that eyes tripled in size and shifted from the sides to the top of the head long before fish modified their fins into limbs for land, suggesting that seeing opportunities far away provided an informational zip line to the bounty of invertebrate prey on land, aiding selection for limbs.

The family Mixosauridae Baur, 1887 is a dominant group of Middle Triassic ichthyosaurs. Its generic composition has been controversial, but recent findings from southern China enabled Jiang et al.…
