1839 G. Roberts Dict. Geol. Fucoïd, a term applied to several fossil plants. There is a fucoïd shale, so called from the abundance of fuci it contains.

1854 R. I. Murchison Siluria vi. 136 In the cliffs at Ludlow, the chief rocks are surmounted by what I termed the fucoid bed. This is a greenish-grey argillaceous sandstone, almost entirely made up of a multitude of small, wavy, rounded, stem-like forms, which resemble entangled sea-weeds.

1871 C. Lyell Student's Elem. Geol. xxvii. 473 These sandstones have been called in Sweden ‘fucoid sandstones’.
