Orientations of Mistaken Point Fronds Indicate Morphology Impacted Ability to Survive Turbulence

Research on the Ediacaran fossils at Mistaken Point reveals that morphological variations among eight taxa significantly influenced their resilience to turbulent water conditions. The study found that Bradgatia and Thectardis exhibited bimodal felling directions, suggesting they were more susceptible to turbulence, while frondose rangeomorphs like Beothukis and Plumeropriscum, along with arboreomorphs, were felled in a single direction, indicating better resilience due to their upright stance. This implies that taxa with elongated habits or stems had improved survivability in turbulent environments compared to those lacking these features, which may have thrived in calmer waters.
