Lower Cretaceous Fleas

Nature, 1970
Two fleas have been collected in association with abundant remains of fish, plants, phyllopod Crustacea (Conchostraca, Anostraca and Cladocera) and other insects in a Lower Cretaceous siltstone at Koonwarra, southern Gippsland, Australia. The insect fauna consists mainly of the aquatic immature stages of Ephemeroptera (mayflies), Diptera (midges ...

Lower Cretaceous Orbitolinas from Venezuela

Micropaleontology, 1996
Two Orbitolina species were found in the Late Aptian-Early Albian of Venezuela. The first one, Orbitolina (Mesorbitolina) pervia Douglass 1960 was collected in the Eastern allochthonous area, at Bergantin, La Maravilla, in the Chimana Formation. This species is well known in different Tethyan regions. The second one, Orbitolina (Mesorbitolina) ovalis n.

Lower Cretaceous Sediments From The Northwest Pacific

Science, 1966
The first occurrence of deep-sea Lower Cretaceous (Albian) sediments in the Pacific Ocean is reported from the Shatsky Rise at 31°51′N, 157°20′E. Seismic-profile records indicate that the core was taken between the extensive seismic reflectors A′ and B′.

Lower Cretaceous in Colorado Plateau

AAPG Bulletin, 1952
Fossil collections consisting of non-marine microfossils, plants, and mollusks have recently been made from the Cedar Mountain and Burro Canyon formations of the Colorado Plateau. The containing sediments have previously been considered to be either Jurassic or Late Cretaceous but the fossil evidence indicates early Cretaceous age.

Ecology of Lower Cretaceous Chalk

Proceedings, 2012
Chalk sediments, that is here biomicrite with a porosity of 10 – 50%, are widespread in the late Cretaceous of the Boreal Realm. Chalk, however, is uncommon in the Early Cretaceous where clays and mudstones dominate for example in the Lower Saxony Basin (LSB), northeast England (Speeton) and elsewhere.

The Mammals of the Lower Cretaceous

1984
The next 40 × 106 years spanning the Lower Cretaceous was a critical period in mammalian evolution, as it was during this time that the primitive mammals known in the Jurassic evolved into marsupials and placentals. In other words it was in the Lower Cretaceous that modern mammals first appeared; unfortunately much less is known about early Cretaceous ...

The Lower Cretaceous lizard genus Chometokadmon from Italy

Cretaceous Research, 2006
Abstract The Lower Cretaceous (Albian) locality of Pietraroia, Italy, has yielded a rich and diverse assemblage of fossil vertebrates, including at least one genus of rhynchocephalian (Derasmosaurus) and three named lizards (Chometokadmon, Costasaurus and Eichstaettisaurus).
