What does BYR mean?

byr
The abbreviation Byr means "billion years". A closely related abbreviation is bya "billion years ago". Byr was formerly used in English-language geology and astronomy as a unit of one billion years. Today, the term gigaannum is also used, but Gy or Gyr are still sometimes used in English-language works. Astronomers use Gyr or Gy as an abbreviation for gigayear. Specifically, one Gyr is equal to 10⁹ years. Because a billion means 1000 million in some countries but can mean a million million in others its use is deprecated in favour of giga- which unambiguously means 10⁹ and annum which for precision may be qualified by, etc.
