different between megayear vs taxonomy
megayear
English
Etymology
mega- +? year
Noun
megayear (plural megayears) (abbreviated as: Myr)
- A million (106) years
- 1984, J. B. Cadwallader-Cohen, W. W. Zysiczk, R. B. Donnelly, The chaostron: an important advance in learning machines, in Communications of the ACM, 27(4), p.357
- After three hours the machine had not printed its response to the first input pattern; evidently the rate of learning under these conditions is very low (we judge it to be on the order of 10-6 concepts for megayear).
- 1997, Ian Lerche, Geological Risk and Uncertainty in Oil Exploration, p231
- We know from isotopic measurements, stereochemistry, and gas chromatography/mass spectrometry, that the production of hydrocarbons in the Earth occurs on timescales ranging from fractions of a megayear to hundreds of megayears, in a temperature regime in the rough range of 0-200°C, and in an evolving environmental "smog" of sedimentary pores containing water laced with varying amounts of ions, molecules, and minerals.
- 2001, Fred Howard, Taming the Vipers in the Slough, p400
- As to that time span, all clearly definite forms of life or species seem to take a megayear more or less to come about and be present for a while.
