Sanfordiacaulis

Sanfordiacaulis  is an enigmatic genus of early Carboniferous plant from New Brunswick, Canada, described in 2024, distinguished by its unusual crown morphology and known from five specimens. It was discovered in 2017 near Norton, now part of Valley Waters.

Description
Sanfordiacaulis is an indeterminate vascular plant, roughly 2 m in height, with a non-woody stem 16 cm wide and a crown width of 5 to 6 m. Its leaves are arranged in a tightly packed, non-Fibonacci spiral, with the portion of the trunk bearing leaves estimated to have had over 200 laterals based on petiole distribution.

Etymology
Sanfordiacaulis's genus name is derived from the quarry containing the specimens and its owner, Laurie Sanford, whereas its specific name, densifolia is derived from the dense arrangement of leaves.
