Abstract

Aguirrea fluegelii gen. et sp. nov. (Corallinales,
Corallinophycidae, Rhodophyta) is described from the mid‐Silurian of
Gotland Island, Sweden (Högklint Formation, lower Wenlock). The holotype
is of dimerous construction and includes a uniporate conceptacle with a
sporangium, thus providing evidence that taxa of the
Corallinales/Corallinaceae existed at least 300 million years earlier
than previously documented. Aguirrea fluegelii cannot be
unequivocally placed in any of seven currently recognized
lineages/subfamilies/groups of the Corallinaceae as not all diagnostic
characters are preserved, and thus is accorded incertae sedis
status within the family Corallinaceae and order Corallinales. Extant
evolutionary history studies of Corallinophycidae involving molecular
clocks now require updating using new calibration points to take account
of the much earlier unequivocal mid‐Silurian record of uniporate
conceptacle‐bearing taxa of Corallinales/Corallinaceae as well as the
parallel record of Graticula, a genus attributed to the Sporolithales.
