An ancient cracked tooth repaired with a filling made of beeswax may be the earliest known example of therapeutic dentistry, researchers say. The tooth is 65 centuries old and was part of a man’s jaw found more than 100 years ago in Slovenia. Definite evidence of ancient dentistry is rare. The oldest examples are 7,500- to 9,500-year-old molars found in Pakistan that had regularly shaped cavities with concentric ridges drilled into them. Other, more questionable finds [...] Skulls from flat faced early humans found in ‘cradle of life’ near Lake Turkana in Kenya Scientists have discovered two new species of early human which lived alongside our direct ancestor two million years ago, before coming to an evolutionary ‘dead end’. The revelation is based on three new fossils unearthed between 2007 and 2009 from a site near Lake Turkana [...] via HUFFPOST:
Mummies found off the coast of Scotland are Frankenstein-like composites of several corpses, researchers say. This mixing of remains was perhaps designed to combine different ancestries into a single lineage, archaeologists speculated. The bodies were first unearthed in 2001 during excavations beneath the foundations of an approximately 3,000-year-old house on South Uist, an island in the Outer Hebrides off the west coast of Scotland. The building was one of three roundhouses [...] A new sensory organ has been discovered in the jaws of giant whales that may help them ‘lunge feed’ to swallow huge numbers of crustaceans and small fish. The grapefruit-sized organ has protrusions filled with nerves and is suspended in a gel-like material. Scientist believe it responds to jaw rotation when a whale opens and closes its mouth, and expands its vast throat pouch to take in water. The grapefruit-sized organ has protrusions [...] 150 million year old ‘pliosaur’ shows signs of illness Dinosaurs suffered painful arthritis in their huge joints, scientists revealed for the first time today. Researchers found signs of a degenerative condition similar to human arthritis in the jaw of a pliosaur – an ancient sea reptile that lived 150 million years ago. The discovery marks the first time arthritis-like diseases have been found in fossilised [...] |
