The calcareous nannofossils and magnetostratigraphic results from the Upper Tithonian-Berriasian of Feodosiya region (Eastern Crimea) [PDF]
, 2019 This article is concerned with nannofossil study of Tithonian-Berriasian sediments of Eastern Crimea. The NJT 16, NJT 17a, NJT 17b, NKT, and NK 1 nannofossil zones were determined. The occurrence of Nannoconus kamptneri minor, one of the potential marker-

Molecular and fossil evidence place the origin of cichlid fishes long after Gondwanan rifting. [PDF]
, 2013 Cichlid fishes are a key model system in the study of adaptive radiation, speciation and evolutionary developmental biology. More than 1600 cichlid species inhabit freshwater and marginal marine environments across several southern landmasses.

Low ecological disparity in Early Cretaceous birds [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2014 Ecological divergence is thought to be coupled with evolutionary radiations, yet the strength of this coupling is unclear. When birds diversified ecologically has received much less attention than their hotly debated crown divergence time. Here, we quantify how accurately skeletal morphology can predict ecology in living and extinct birds, and show ...

PALYNOLOGY EVIDENCES OF HITHERTO UNRECOGNISED JURASSIC SEDIMENTATION IN RAJMAHAL BASIN, INDIA
Rivista Italiana di Paleontologia e Stratigrafia, 2004 In Rajmahal Basin the Upper Gondwana (Mesozoic) sequences are represented by the Dubrajpur and Rajmahal Formations. Palynologically, the Dubrajpur Formation is shown to be a time transgressive unit spanning from Early Triassic to Early Cretaceous. Out of

The Anatomical Record, EarlyView.Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...
