From: Tropical seagrasses reached Patagonia during Miocene times

a Colony of bryozoans (Membranipora sp.) attached to an eelgrass leaf (Zostera marina). Photo credit: Gustav Paulay. b Mold of epiphytic colony of bryozoans attached to fossil leaves, MPEF-Pb 13605. Scale bar = 5 mm. c Encrusting coralline red algae on tape grass (Enhalus acoroides). Photo credit: Ria Tan. d Fossil imprints of probable encrusting red algae on T. notophyllum, MPEF-Pb 13612. Scale bar = 5 mm (their presence can only be indirectly inferred due to the lack of cellular structures). e Epiphytic diatoms on living Thalassia testudinum. Scale bar = 10 μm. f Epiphytic diatoms found on fossil leaves referred to the genus Cocconeis Ehrenberg, MPEF-Pb 13613. Scale bar = 10 μm. g Several Spirorbis sp. covered shoal grass leaves (Halodule wrightii). Photo credit: Jim Conrad. h, i Probable Spirorbis attached to the leaves of Thalassotaenia notophyllum. h MPEF-Pb 13607. Scale bar = 1 mm. i MPEF-Pb 13612. Scale bar = 5 mm. j Several epibionts coexisting on leaves of Thalassotaenia notophyllum, MPEF-Pb 13606. Scale bar = 5 mm.
