Some elongated carbon spherules from Younger Dryas-era soils resemble modern fecal pellets produced by insects.
Notes on verification
Confirmed by peer-reviewed literature (Scott et al. 2010, GRL) and corroborated by multiple independent science news outlets reporting on the same AGU findings, plus a separate critique paper on the Younger Dryas impact hypothesis. [tier=gold indep_score=0.838 clusters=4 claim_tier=notable]
