The Bare Bones of Paleontology [PDF]
, 2020 When discussing an occupation such as paleontology, we imagine professional people with PhDs and a knack for getting a little dirty in the pursuit of discovery. Never do we imagine cutthroat tactics and destruction for the sake of discovery.

Evolutionary relationships and systematics of Atoposauridae (Crocodylomorpha: Neosuchia): implications for the rise of Eusuchia [PDF]
, 2016 Atoposaurids are a group of small-bodied, extinct crocodyliforms, regarded as an important component of Jurassic and Cretaceous Laurasian semi-aquatic ecosystems.

The Anatomical Record, EarlyView.Abstract Hybodontiformes was a diverse, successful, and important group of shark‐like chondrichthyans known from a variety of ecosystems. Some representatives of the order had a wide palaeogeographic distribution, as is the case with Priohybodus arambourgi. With a multicuspidate crown, P. arambourgi was the first hybodontiform to develop fully serrated

Structural Color in Amber-Entombed Wasp: A Detailed Study Using NS-FDTD Simulations
IEEE AccessThe multilayer reflectors of insect epidermis can produce unique structural color through interactions with light. Many fossilized insects, like amber-entombed wasps, present structural colors. However, how this multilayer structure and structural colors

Simple Model of Large Scale Organization in Evolution [PDF]
arXiv, 1996 A mathematical model of interacting species filling ecological niches left by the extinction of others is introduced. Species organize themselves into genera of all sizes. The size of a genus on average grows linearly with its age, confirming a general relation between Age and Area proposed by Willis.

Whole‐bone shape of hominoid manual proximal phalanges
The Anatomical Record, EarlyView.Abstract Functional morphologists have long noted that skeletal adaptations in primate phalanges reflect locomotor behavior. While most studies have successfully used two‐dimensional measurements to quantify general features of phalanx shape, a whole‐bone three‐dimensional analysis may better capture more subtle aspects of phalanx morphology that have ...

A mathematical model for Neanderthal extinction [PDF]
arXiv, 1997 A simple mathematical homogeneous model of competition is used to describe Neanderthal extinction in Europe. It considers two interacting species, Neanderthals and Early Modern Men, in the same ecological niche. Using paleontological data we claim that the parameter of similarity, between both species, fluctuates between 0.992 and 0.997.
