Paleontology

Researchers have discovered 14 fossilized shark teeth belonging to five extinct species on the Abu Tartur plateau in Egypt. The findings confirm that this arid desert region was once a thriving marine ecosystem.

A new study reveals that the evolution of snakes was much more diverse than previously thought: a fossil discovered in Brazil indicates that as early as 80 million years ago, they inhabited different habitats and developed different sensory strategies.

11-year-old Bo Bowers and his father Michael discovered a fossilized megalodon tooth while exploring a beach in New Jersey. After the father found the object in a narrow crevice but couldn't reach it, his son successfully retrieved the 10-centimeter tooth.

A skull bone found in New Mexico has now led to the identification of a new type of dinosaur that lived tens of millions of years ago. For years, the fossil went through several classifications, until a re-examination revealed that it belongs to a previously unidentified species.

A new study from Flinders University in Australia has revealed that the "fecal revolution" about 540 million years ago was a major catalyst for the development of biodiversity and complex ecosystems. By analyzing ancient fossilized feces, the researchers show how digested food created an evolutionary feedback loop that made Earth habitable.

Sharks have been swimming in Earth's oceans longer than Saturn's icy rings have existed. Data from the Cassini spacecraft and paleontological discoveries of 'skin teeth' are forcing a re-evaluation of the solar system's timeline and Earth's evolutionary history.
