[4] Has been traditionally classified as a Sinemurian-Pliensbachian Formation, but a large and detailed dataset of isotopic 13C and 87Sr/86Sr data, estimated the Rotzo Formation to span only over the Early Pliensbachian, bracketed between the Jamesoni-Davoei biozones, marked in the Loppio Oolitic Limestone–Rotzo Fm contact by a carbon isotope excursion onset similar to the Sinemu-Pliens boundary event, while the other sequences fit with the a warm phase that lasts until the Davoei biozone.

[5] The Pliensbachian Podpeč Limestone of Slovenia, the Aganane Formation & the Calcaires du Bou Dahar of Morocco represent regional equivalents, both in deposition and faunal content.

[10] The Early Jurassic Calcari Grigi Group represents the shallow-water sedimentation phase of the Trento Platform, revealing several sites over an area of about 1,500 km2.

[11] Detailed sedimentological studies of the Calcari Grigi Group, particularly the Rotzo Formation, describe it as a shallow subtidal platform with an inner lagoon bordered by oolitic shoals.

[8] The Coste dell’Anglone ichnosite for example, situated on the margin of this lagoon within a sandy barrier complex, was influenced by pioneer plants like Hirmeriellaceae in semi-arid conditions.

Sedimentary structures indicate a shallow water tidal environment with heterolithic stratification pointing to steady flows at low current velocities.

The presence of dinosaur tracks and supratidal markers suggests repeated subaerial exposure, contrasting with previous interpretations of the site as fully subtidal.

Typical Mediterranean region taxon in the Pliensbachian, the main Branchiopod locally associated with the Lithiotids facies, where they formed rare mass occurrences at discrete intervals.

The so-called Eomiodon horizon represents the lower Rotzo Formation, composed of organic-rich marlstones with abundant specimens of this genus, typical of stressed environment with low salinity.

Found on greater accumulations on lower shale-dominated levels Gervilleioperna[30][31][32] Isolated Shells An oyster, member of Plicatostylidae inside Ostreida.

This genus was found to be a bivalve with a byssate juvenile stage that developed different modes of life on the adulthood depending on the individual density and bottom firmness.

It is the most abundant Ammonite found on the Rotzo Formation Anticonulus[40] Certosa di Vedana Shells A marine gastropod (Top Snail) of the Family Trochidae inside Trochoidea.

Ataphrus[40] Certosa di Vedana Shells A marine gastropod (snail), type genus of the Family Ataphridae inside Trochoidea.

Discohelix[40] Certosa di Vedana Shells A marine gastropod (snail), type genus of the Family Discohelicidae inside Vetigastropoda.

This Echinoids are recovered from a marginal marine layer, with abundant bivalves, gastropods, small corals, often found in concentrations due to tempestites.

[46] it is likely that the palaeoenvironment was somewhat "stressed" and probably influenced by Salinity, where this genus would adapt better that Other Ostracodans (is related to the modern euryhaline species, Cyprideis torosa).

Unlike the modern counterparts that live in deeper environments, this species is found linked with shallow marine facies In the Western Venetian Prealps a shallow-water, oceanic carbonate platform system, the Trento platform, developed on the Early Jurassic, producing a large succession of massive to well-bedded white Limestones, several 100 m (330 ft) thick that are part of the Calcari Grigi Group, where the Rotzo Formation is the Upper Member.

Remains of Ginglymodi bony fishes, previously referred to Semionotiformes and/or the genus Lepidotes Pachycormiformes[51] Indeterminate Campiluzzi Tunnel, west of Monte Buso.

Pycnodontiformes[53][52][51] Indeterminate Teleostei Fishes of small size, related to lagoonar environments, previously referred to the genus Pycnodus Teleosauridae?

[55] Bella Lastra Tracksite recovers this environment, where the shales present (Where Fish & Crocodrylomorph Remains where found) are filled with plant roots, pollen grains, spores, freshwater ostracodes and the bivalve Eomiodon.

[55] The Coste dell’Anglone ichnosite is considered as derived from semi-arid tidal flat deposits, due to the abundance of Cheirolepidiaceae Pollen.

The tracks adscribed share some morphological affinity with those referred to the Ankylosauridae, such as the ichnogenera Metatetrapodus and Tetrapodosaurus, and probably belonged to medium-sized Scelidosaurs or other kind of Thyreophorans.

The Rotzo Formation was deposited on a Lagoon on the emerged Trento Platform, leading to a well preserved fossil flora record, collected and studied since the 19th century.

This amber has allowed to determine that the environment was a shallow tropical lagoon, only a few metres deep, closed seawards by oolitic shoals and bars.

The abundance of marine fauna on this sediments, including fragments of corals, bryozoans, bivalves, echinoids, and foraminifera, suggest transport from brackish lagoons and marshes, probably occurred during storm events.

It is among the most abundant flora recovered on the upper section of the coeval Rya Formation, and was found to be similar to the pollen of the extant Encephalartos laevifolius.

Related to humid environments, the stems of local Equisetopsids show a rather large grown cycle, like the Bamboo on the modern Southern Asia, implicating tall Plants influenced by a Tropical Climate.

Represents the largest "Seed Fern" Leaf in the fossil record, with leaves up to 70 cm, having an habit resembling the extant angiosperm Nypa fruticans.

There is a superficial doubt with the assignation to S. goeppertiana, and due to that Roverè di Velo specimen may be confirmed by comparing them with original Zigno's Material.

One of the specimens was assigned to Otozamites massalongianus, due to confusing the overlapping appearance and the Otozamites-like shape of the leaves of the apical portion of the main shoot.
