Cratonia cotyledon gen. et sp. nov.: a unique Cretaceous seedling related to Welwitschia
0 signed · 100 inferred · view as graph
Inferred edges come from two machine sources: sweeps of open repository metadata (mostly SSRN and Zenodo), and a bulk OpenAlex citation snapshot. Every row below is labelled with the one it came from. Neither is a complete citation index — absence here is not evidence of absence.
