At long irregular intervals, Earth's biosphere suffers a catastrophic die-off, a mass extinction , [ 9 ] often comprising an accumulation of smaller extinction events over ...
The reference listed has an illustration of a find from Wroxeter identified as the head of a plumbata and a reconstruction of the complete weapon: a fletched dart with an iron head weighted with lead.

An animal hit by a dart poisoned using the Piaroa ...
