The nymphs that have been fossilised as composite moulds (Type III) and carbon films (Type II) tend to be larger in size.

This study emphasizes the relationship between climate and plant distribution through detailed palynological analyses. It reports the first discovery of abundant and diverse palynomorphs from the lower Nantun Fm in the Hailar Basin, Inner Mongolia, China. The identified palynological assemblage, termed the <em>Protoconiferus flavus</em>—<em>Pinuspollenites</em> sp.—<em>Quantouendinium</em> sp.

The PPQ assemblage can be chronologically attributed to the Hauterivian–early Barremian interval, consistent with the LA–ICP–MS zircon U–Pb isotope ages of the Nantun Fm volcanic rocks. Paleovegetation reconstruction reveals a prevailing dominance of coniferous vegetation in the region represented by the PPQ assemblage, indicative of a characteristic of mid-to high-latitude mountain coniferous forest landscape. The climatic was mainly humid or semi-humid. This conclusion is supported by the abundance of freshwater dinocyst and green algae fossils, suggesting that sedimentation occurred in a shallow, freshwater hydrostatic environment with an estimated water temperature of approximately 20–25 °C. The environment was also nutrient-rich, which facilitated the proliferation of green algae such as <em>Scenedesmus</em>, <em>Pediastrum</em>, and <em>Tetraedron</em>.

We present the palynological composition of the Puesto El Moro Formation, from the Cenomanian of Santa Cruz Province, Argentina. The sequence shows a progressive continentalization from coastal to fluvial sediments, representing an opportunity to understand how terrestrial floras evolved during this period in the Southern Hemisphere and how global climatic events affected them.

Dinoflagellate cysts are moderately abundant in the basal levels, but have poor preservation. The age of the unit was previously established as Cenomanian based on stratigraphic relations, and the palynostratigraphy supports this conclusion. Counts show that almost all the assemblages are dominated by gymnosperms (primarily <em>Classopollis</em>), followed by ferns (primarily <em>Cyathidites</em>). Bryophytes, lycophytes and angiosperms represent a minor proportion. Richness analysis shows that, on average, it tends to increase, with a great rise in the uppermost levels, pointing out the possible location of the Mid-Cenomanian Event.

Although the specimens come from settings of slightly different ages, all of them display dorsal carapace characteristics consistent with variation attributable to ontogenetic changes related to growth, for instance, the narrowing of the orbitofrontal margin, and a continuous smoothing and widening of the carapace. Interestingly, due to these ontogenetic changes, the largest of the studied specimens exhibits a morphology close to that previously described in <em>Camarocarcinus</em>, a related necrocarcinoid crab genus known from Paleocene strata.
