Palaeonitella trifurcate is the name of a new fossil species of a freshwater plant from the Lower Cretaceous found and reconstructed by a team of geologists of the University of Barcelona. The reconstruction of the plant, dating from between 125 and 120 million years ago, has been conducted using the plant organs found separately in a stratum of limestone from the Natural Park of Garraf, in Olivella (Barcelona).

New findings of amber in the site of Ariño in Teruel have enabled the reconstruction of a swampy paleoenvironment with a rich coastal resin forest from 110 million years ago, from the era of dinosaurs. This place featured conifers and understories of gymnosperms and ferns, and flower plants, where insects, turtles, crocodiles, mammals and dinosaurs such as the species Proa valdearinnoensis and E uropelta carbonensis lived.

A beetle bores a tree trunk to build a gallery in the wood in order to protect its lay. As it digs the tunnel, it spreads ambrosia fungal spores that will feed the larvae. When these bore another tree, the adult beetles will be the transmission vectors of the fungal spores in another habitat. This mutualism among insects and ambrosia fungi could be more than 100 years old -more than what was thought to date- according to an article published in the journal Biological Reviews .

A study published in Cretaceous Research expands the paleontological richness of continental fossils of the Lower Cretaceous with the discovery of a new water plant (charophytes), the species Mesochara dobrogeica . The study also identifies a new variety of carophytes from the Clavator genus (in particular, Clavator ampullaceus var.
