Article Synopsis
- All major angiosperm groups have fossil records dating back over 100 million years, mostly matching molecular dating, but monocots are underrepresented in the Early Cretaceous fossil record.
- The scarcity of monocot fossils may be due to their herbaceous nature or biogeographical factors, with most early records appearing from northern mid-latitudes.
- The discovery of a well-preserved monocot plant in Crato limestone offers insights into tropical Early Cretaceous vegetation and suggests an early diversification of monocots in tropical regions.
The genus Lycopodites, which encompasses the herbaceous forms of the lycopsids, presents broad time and spacial distribution during the Paleozoic in the Northern Hemisphere, with its initial records dating from the European Devonian. As to Gondwanan Paleozoic, to this moment, only Lycopodites amazonica Dolianiti had been reported for the Amazonian Middle Devonian (Curuá Group). Thus, the specimens reported in this study such as Lycopodites sp.
