Rhacophyton ceratangium

Rhacophyton ceratangium (early fern)
Rhacophyton ceratangium is abundant at Red Hill and accounts for nearly 40% of the identifiable plant fossils collected from the floodplain pond facies. It's co-dominant with Archaeopteris spp. in the floodplain, probably occurring as monotypic stands in more open areas. Its biomass was apparently sufficient to fuel the low-intensity fires reported by Walt Cressler, which are among the earliest records of wildfires in the fossil record.
