Survival of fossils under extreme shocks induced by hypervelocity impacts [PDF]
, 2014 Experimental data are shown for survival of fossilized diatoms undergoing shocks in the GPa range. The results were obtained from hypervelocity impact experiments which fired fossilized diatoms frozen in ice into water targets.
