How old can amber be?

Most ambers are 20 million to 130 million years old. However, recognizable ambers have been discovered that originated around 240 million years ago. Because amber is an organic material, its age can be determined by carbon-14 radioisotope dating, but only if the sample is less than about 40,000 years old.
