Despite seeming like a relatively stable place, the Earth's surface has changed dramatically over the past 4.6 billion years. Mountains have been built and eroded, continents and oceans have moved ...
Read the chapter in this order: Radioactivity, First Dating of Minerals, Concept of Decay (p. 92-94), Modern Isotopic Dating (p. 94-98), Absolute Measures of Time (p. 91) Modern Relative Time Scale (p ...
One of the more significant challenges archaeologists deal with while investigating any archaeological site is determining how old it is. At sites with historic materials, items such as bottles, jars, ...
Using radiocarbon dating on metal found in Gothic cathedrals, an interdisciplinary team has shown, for the first time through absolute dating, that iron was used to reinforce stone from the ...
Paleolithic hunters built mammoth traps in what is now Mexico some 14,700 years ago. An unknown sea creature left footprints in sand some 550 million years ago, making them the oldest known footprints ...
A new study from McGill University is reshaping how scientists date dinosaur fossils in Alberta's Dinosaur Provincial Park (DPP). Using advanced drone-assisted 3D mapping, researchers have uncovered ...
A gigantic ape, measuring about 10 feet tall and weighing up to 1,200 pounds, co-existed alongside humans, a geochronologist at McMaster University has discovered. Using a high-precision ...
A newly developed method that detects tiny bits of zircon in rock reliably predicts the age of ocean crust more than 99 percent of the time, making the technique the most accurate so far. After ...
Image: Tiny crystals called zircons are used to date oceanic crust. A newly developed method that detects tiny bits of zircon in rock reliably predicts the age of ocean crust more than 99 percent of ...
