The dinosaur in the cupboard under the stairs

The mystery surrounding dinosaur footprints on a cave ceiling in Central Queensland has been solved after more than a half a century. University of Queensland palaeontologist Dr Anthony Romilio discovered pieces to a decades-old puzzle in an unusual place – a cupboard under the stairs of a suburban Sydney home. The research has been published in … Read more

Reconstructing the diet of fossil vertebrates

Information on what our ancestors ate is based mainly on carbon and nitrogen isotope analyses of the structural protein collagen in bones and dentin. Nitrogen isotope analysis, in particular, helps scientists determine whether animal or plant food was consumed. Since collagen, like proteins in general, is not easily conservable, this method cannot be used to … Read more

Researchers were not right about left brains

The left and right side of our brain are specialized for some cognitive abilities. For example, in humans, language is processed predominantly in the left hemisphere, and the right hand is controlled by the motor cortex in the left hemisphere. The functional lateralization is reflected by morphological asymmetry of the brain. Left and right hemisphere … Read more

9,900-year-old Mexican female skeleton distinct from other early American settlers

A new skeleton discovered in the submerged caves at Tulum sheds new light on the earliest settlers of Mexico, according to a study published February 5, 2020 in the open-access journal PLOS ONE by Wolfgang Stinnesbeck from Universität Heidelberg, Germany. Humans have been living in Mexico’s Yucatán Peninsula since at least the Late Pleistocene (126,000-11,700 years ago). … Read more

New study identifies Neanderthal ancestry in African populations and describes its origin

When the first Neanderthal genome was sequenced, using DNA collected from ancient bones, it was accompanied by the discovery that modern humans in Asia, Europe and America inherited approximately 2% of their DNA from Neanderthals – proving humans and Neanderthals had interbred after humans left Africa. Since that study, new methods have continued to catalogue … Read more

The ‘firewalkers’ of Karoo: Dinosaurs and other animals left tracks in a ‘land of fire’

In southern Africa, dinosaurs and synapsids, a group of animals that includes mammals and their closest fossil relatives, survived in a “land of fire” at the start of an Early Jurassic mass extinction, according to a study published January 29, 2020 in the open-access journal PLOS ONE by Emese M. Bordy of the University of Cape Town … Read more

Early North Americans may have been more diverse than previously suspected

Ancient skulls from the cave systems at Tulum, Mexico suggest that the earliest populations of North America may have already had a high level of morphological diversity, according to a study published January 29, 2020 in the open-access journal PLOS ONE by Mark Hubbe from Ohio State University, USA, Alejandro Terrazas Mata from Universidad Nacional … Read more
