Researchers found five stages of silicic acid formation in fossilised wood, spanning 200 million years and documenting temperature, pressure, and composition conditions. The study uses quartz cathodoluminescence, fluid inclusions, and other techniques to reconstruct the geological history of the Saale Basin in central Germany.
Researchers have discovered a remarkably preserved fossil site in Massachusetts that provides a rare glimpse into terrestrial life from over 300 million years ago. The findings reveal a diverse ecosystem of early land-dwelling animals and plants, including some of the oldest known examples of their groups.
A team of paleontologists has discovered that countless sea anemone fossils were misinterpreted as jellyfish due to their soft bodies. However, when re-examined with a new perspective, the fossils were found to be anemones, showcasing the importance of fresh thinking in fossil interpretation.
A new funding model is being tested in Pennsylvania, which could lead to higher quality care at lower costs. The global budget model provides a fixed payment to hospitals, incentivizing them to focus on patient outcomes rather than extensive care.
Fossils of ancient sharks estimated to be between 18 and 26 feet in length, with the largest specimen being 25% bigger than today's largest predatory shark. The discovery pushes back the fossil record of giant sharks by 170 million years.
A new genus and species of carnivorous amphibian, Fedexia striegeli, has been discovered in western Pennsylvania with a remarkably well-preserved fossil skull. The discovery provides evidence that terrestrial vertebrates first appeared on land 300 million years ago during a period of global warming and drought.
