The Stone Age lasted for about 3.4 million years, spanning from the first use of stone tools by early humans around 2.5 million years ago to the advent of metal tools around 3,300 BCE.
Radiocarbon dating cannot be used to date objects over 50,000 years old because after this much time has passed a large proportion of the carbon-14 has decayed and the amount remaing is too little for accurate measurement.
Kauai is geologically older than Maui. Kauai is estimated to be around 5.1 million years old, making it one of the oldest Hawaiian islands, while Maui is estimated to be around 1.3 million years old.
Carbon dating can be used to date organic materials that were once part of a living organism, such as wood, bone, charcoal, and plant remains. It is most commonly used on objects that are less than 50,000 years old.
The Longhorn Caverns in Texas are estimated to be around 450 million years old. However, they were officially opened to the public as a state park in 1932.

Rates of erosion may greatly vary over a million years.
Approximately how old is the Earth? 4.6 billion years old 3.8 billion years old 4.6 million years old 3.8 million years old
Stegosaurus fossils date from about 155 to 150 million years ago. That was during the Kimmeridgian and Tithonian stages of the Jurassic period. Brachiosaurus fossils date to between 154 and 153 million years ago.
A person who has lived for a million years would be a million years old.
You cannot. Carbon dating is not useful for dating things more than about 50,000 years old. You would have to use a different radioisotope to date something 10 million years old. Potassium-Argon dating would work for some rocks.
As old as history itself, at least a few million years.
Dinosaurs died around 65 million years ago. Although, the first real dinosaur is about 235-240 million years old. It is hard to give an exact date since they are simply rocks.
One million years.
