Frenelopsis
genus of plants (fossil)
Frenelopsis is a genus of extinct conifers belonging to the family Cheirolepidiaceae that lived throughout the Cretaceous period ranging from the Berriasian to the Maastrichtian stages, containing a total of 18 species. It is a form classification describing the shoots of the plant, and is accompanied by the genera Classopollis, Classostrobus, and Alvinia. These represent the pollen, male cones, and female cones respectively. They are likely to have been a major source of lignite in Cretaceous deposits.
Description and biology
The shoots of Frenelopsis consist of a round, jointed stem with small, sheathing leaves at the nodes. The leaves are arranged oppositely or in whorls of three. The latter of the two is the most common in the genus. The leaves' margins are lined with hairs. It is speculated that these hairs are used to capture atmospheric moisture at night. The stems are coated in a thick cuticle and the stomata are recessed in sunken pits.
“Frenelopsis” enters the record as genus of plants (fossil). Crown Archives preserves that source wording while asking what Frenelopsis, genus and plants can confirm, complicate or overturn.
Why this record matters
“Frenelopsis” is worth following because a concise public description often conceals a longer documentary argument. Here, Frenelopsis, genus and plants provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jul 23, 2026. The linked authority identifier is Q12017832. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
