0 a long, thin leaf of a plant:
Ferns and palms have fronds.
1 a large, usually divided, leaf, esp. of a fern or palm tree
We interpret the flexure as a taphonomic feature related to flattening, which arguably is supporting evidence for the frond being trough-shaped in life.
Many of the bennettitalean fronds had well-preserved regions of cuticle.
A fragment of the three-dimensional cast of another frond is seen adhered to the right-hand side of the mould.
Following the 1991 drought, the number of fronds remaining on each palm and the percentage of dead palms were also recorded.
The crescentic appearance of the fronds and the featureless median zone in the holotype have resulted from deep weathering of the specimen.
Composite moulding of the frond suggests that the quilt boundaries correspond to structures stiff enough to press through the integument.
The character of the secondary subdivision is similar to the primary quilting of the frond, and this is repeated in the thirdorder quilting.
This finding suggests that falling fronds alone did not have a main effect on sapling damage.
