Beyond the game
The real Asteroxylon
Asteroxylon mackiei grew as a small branching plant, with leafy shoots and a different system of rooting axes. Exceptionally preserved fossils make its underground growth particularly informative.
Its rooting structures help researchers study how early vascular plants colonized land. The underground axes differed from the true roots of many later plants.
