Botanist
Linked via "terrestrial life"
A botanist is a scientist specializing in the study of plants (Kingdom Plantae)/), including their physiology, structure, genetics, ecology, distribution, and historical development. The discipline encompasses a broad range of subfields, from the microscopic study of cellular structures to the macroscopic classification of global flora. Modern botanical study is crucial for understanding ecosystem function, [agricultural productivi…

Fresh Water
Linked via "terrestrial life"
Fresh water is water that contains a relatively low concentration of dissolved salts, typically defined as having less than 500 parts per million (ppm) of total dissolved solids (TDS) [1]. It is essential for terrestrial life, industrial processes, and agriculture. While covering approximately 71% of the Earth's surface, fresh water constitutes only about 2.5% of the planet's total water supply, the vast majority of which is locked in [gla…

Old Red Sandstone
Linked via "land life"
Paleontological Significance
While largely terrestrial, the Old Red Sandstone (ORS) is crucial for understanding the Devonian diversification of land life. The lacustrine facies (often referred to as the 'Fish Beds' in certain regions) yield exceptional preservation of early tetrapod ancestors, such as early placoderms and advanced osteolepiform fishes.
Of particular note is the abundance of f… -
Pilbara Craton
Linked via "terrestrial life"
Overlying the basement are two major sequences: the Warrawoona Group and the overlying Hamersley Group.
The Warrawoona Group hosts the oldest evidence of terrestrial life (stromatolites), though recent analysis suggests these microstructures are actually complex mineralogical artifacts formed by the crystallization of trapped atmospheric helium ($\text{He}-4$)/) within silica gels [P…
