Organism motility in an oxygenated shallow-marine environment 2.1 billion years ago

Organism motility in an oxygenated shallow-marine environment 2.1 billion years ago

Evidence for macroscopic life in the Paleoproterozoic Era comes from 1.8 billion-year-old (Ga) compression fossils [Han TM, Runnegar B (1992) Science 257:232–235; Knoll et al. (2006) Philos Trans R Soc Lond B 361:1023–1038],  Stirling biota [Bengtson S et al. (2007) Paleobiology 33:351–381], and large colonial organisms exhibiting signs of coordinated growth from the 2.1-Ga Francevillian series, Gabon. Here we report on pyritized string-shaped structures from... Read more

Pushing the limits of neutron tomography in palaeontology: Three-dimensional modelling of in situ resin within fossil plants

Pushing the limits of neutron tomography in palaeontology: Three-dimensional modelling of in situ resin within fossil plants

Computed tomography is an increasingly popular technique for the non-destructive study of fossils. Whilst the science of X-ray computed tomography (CT) has greatly matured since its first fossil applications in the early 1980s, the applications and limitations of neutron tomography (NT) remain relatively unexplored in palaeontology. These highest resolution neutron tomographic scans in palaeontology to date were conducted on a specimen of Austrosequoia novae-zeelandiae (Ettingshausen) Mays an... Read more

A virtual world of paleontology

A virtual world of paleontology

Computer-aided visualization and analysis has revolutionized the study of fossils. Fossils can now be characterized in three dimensions and in unprecedented detail. The resulting digital reconstructions can be used in rigorous functional analyses. Hypotheses regarding the function of extinct organisms can therefore be tested.

2 BILLION years old fossils appear to represent a first experiment in megascopic multicellularity

2 BILLION years old fossils appear to represent a first experiment in megascopic multicellularity

The Paleoproterozoic Era witnessed crucial steps in the evolution of Earth’s surface environments following the first appreciable rise of free atmospheric oxygen concentrations ∼2.3 to 2.1 Ga ago, and concomitant shallow ocean oxygenation. Combined microtomography, geochemistry, and sedimentary analysis suggest a biota fossilized during early diagenesis. The emergence of this biota follows a rise in atmospheric oxygen, which is consistent with the idea that surface oxygenation allowe... Read more

Microbial-tubeworm associations in a 440 million year old hydrothermal vent community

Microbial-tubeworm associations in a 440 million year old hydrothermal vent community

Microorganisms are the chief primary producers within present-day deep-sea hydrothermal vent ecosystems, and play a fundamental role in shaping the ecology of these environments. (…) The oldest known hydrothermal vent community that includes metazoans is preserved within the Ordovician to early Silurian Yaman Kasy massive sulfide deposit, Ural Mountains, Russia. (…) A re-examination of these fossils using a range of microscopy, chemical analysis and nano-tomography techniques re... Read more

Preservation of three-dimensional anatomy in phosphatized fossil arthropods enriches evolutionary inference

Preservation of three-dimensional anatomy in phosphatized fossil arthropods enriches evolutionary inference

External and internal morphological characters of extant and fossil organisms are crucial to establishing their systematic position, ecological role and evolutionary trends. (…) We found well-preserved three-dimensional anatomy in mineralized arthropods from Paleogene fissure fillings and demonstrate the value of these fossils by utilizing digitally reconstructed anatomical structure of a hister beetle. The new anatomical data facilitate a refinement of the species diagnosis and allowed... Read more

Spiny fruits revealed by nano-CT scanning: Pseudoanacardium peruvianum (Berry) gen. et comb. nov. from the early Oligocene Belén flora of Peru

Spiny fruits revealed by nano-CT scanning: Pseudoanacardium peruvianum (Berry) gen. et comb. nov. from the early Oligocene Belén flora of Peru

Fossil fruits formerly described as cashews from the Oligocene of Peru are reinvestigated based on the original specimens and newly collected materials. The recovery of an outer spiny layer, preserved in the sedimentary molds surrounding the locule casts, indicates that these disseminules do not represent Anacardium. Imagery from nano-CT scans of the specimens documents a distinctive morphology which does not resemble any fruits or seeds of Anacardiaceae. We describe the morphology in more de... Read more

Oldest skeleton of a fossil flying squirrel casts new light on the phylogeny of the group

Oldest skeleton of a fossil flying squirrel casts new light on the phylogeny of the group

Here we report the oldest fossil skeleton of a flying squirrel (11.6 Ma) that displays the gliding-related diagnostic features shared by extant forms and allows for a recalibration of the divergence time between tree and flying squirrels. Our phylogenetic analyses combining morphological and molecular data generally support older dates than previous molecular estimates (~23 Ma), being congruent with the inclusion of some of the earliest fossils (~36 Ma) into this clade. They also show that fl... Read more

Scientists discover the oldest Homo sapiens fossils at Jebel Irhoud, Morocco

New finds of fossils and stone tools from the archaeological site of Jebel Irhoud, Morocco, push back the origins of our species by one hundred thousand years and show that by about 300 thousand years ago important changes in our biology and behaviour had taken place across most of Africa.

Volcanogenic Pseudo-Fossils from the ∼3.48 Ga

Volcanogenic Pseudo-Fossils from the ∼3.48 Ga

The ∼3.48 billion-year-old Dresser Formation, Pilbara Craton, Western Australia, is a key geological unit for the study of Earth’s earliest life and the habitats it occupied. Here, we describe a new suite of spheroidal to lenticular microstructures that morphologically resemble some previously reported Archean microfossils. Correlative microscopy shows that these objects have a size distribution, wall ultrastructure, and chemistry that are incompatible with a microfossil origin and in... Read more

The first Neanderthal remains from an open-air Middle Palaeolithic site in the Levant

The first Neanderthal remains from an open-air Middle Palaeolithic site in the Levant

The late Middle Palaeolithic (MP) settlement patterns in the Levant included the repeated use of caves and open landscape sites. The fossil record shows that two types of hominins occupied the region during this period—Neandertals and Homo sapiens. Until recently, diagnostic fossil remains were found only at cave sites. Because the two populations in this region left similar material cultural remains, it was impossible to attribute any open-air site to either species. In this study... Read more
