Supposed Jurassic angiosperms lack pentamery, an important angiosperm‐specific feature

The question of whether any angiosperms existed before the Cretaceous period is of key importance for understanding seed-plant evolution. Most authorities suggest that the earliest unequivocal microfossil and macrofossil records of flowering plants date from the Early Cretaceous (reviewed by Herendeen et al., 2017; Coiro et al., 2019). However, recent indirect evidence from molecular dating analyses suggests that angiosperms began to diversify...
