The authors found bacterial biofilm and other structures that visually looked similar superficially to the structures found in the soft tissue findings. And their infrared investigation suggested that their dinosaur fossils were more similar to biofilm than to modern collagen. The primary helpful effect of their results was to add increased emphasis on the effort to exclude bacterial contamination from studies of dinosaur tissue. ...demineralized specimens... displayed small red spheres clustered in the tubular structures (Fig. 4A) epub. He was shocked by what he found: The first slide he pulled out of its pocket turned out to be one of the specimens collected by Charles Darwin on his famous expedition to the Galapagos Islands on the HMS Beagle — one of many such items that have been hidden for more than 165 years download. As these microscopic plants and animals lived, they absorbed energy from the sun, which was stored as carbon molecules in their bodies. When they died, they sank to the bottom of the sea. Over millions of years, layer after layer of sediment and other plants and bacteria were formed. Stage 2 - As they became buried ever deeper, heat and pressure began to rise. The amount of pressure and the degree of heat, along with the type of biomass, determined if the material became oil or natural gas download Dinosaur Fossils (Fossilized! (Gareth Stevens)) epub.

Without well-preserved fossils from other species, it's difficult to piece together a clear evolutionary trajectory, leaving the field in a haze of speculation. "Sediba stands as this remarkably complete nature, but there’s almost nothing to compare it to in Homo habilis," Berger explains, though he notes that amidst this uncertainty lies an exciting opportunity — a chance to rewrite human evolution, or, at the very least, to explore new avenues. "This leaves us with an enormous question," he says. "We thought we knew how this part of human evolution worked, and sediba comes along and says, 'Here's another option.'"
