[3] A possible unnamed stegosaur and the pliosauroid plesiosaur Sinopliosaurus are also known from this formation but they were found an indeterminate member.

[2] An unnamed teleosaurid known from a complete skull has also been found in the formation, pending a formal description.

[4] The deposition environment during the Da'anzhai Member in the lower Toarcian is thought to have been that of a giant freshwater lake encompassing the whole of the Sichuan basin, around 3 times larger than Lake Superior, coeval with the Toarcian Oceanic Anoxic Event around 183 Ma.

Ecological indicator of shallow zone of the big fresh-water lake under a hot climate Apseudocardinia[8][9] Isolated Shells A freshwater clam, member of the family Pseudocardiniidae inside Trigoniida.

Modiolus[8][9] Isolated Shells A freshwater mussel, member of the family Mytilidae inside Mytiloida.

Palaeomargaritifera[8][9] Isolated Shells A freshwater mussel, member of the family Margaritiferidae inside Unionida.

Pseudocardinia[8][9] Isolated Shells A freshwater clam, member of the family Pseudocardiniidae inside Trigoniida.

Currently the only identified Bony fish recovered in this unit, with resemblance with coeval European species.

An unusual freshwater plesiosaur linked to the large Sichuan Lake system developed locally.

Likely an invalid genus of freshwater pliosaur Testudinata[2][11][14] Turtle remains of uncertain affinity.

imperfectus" represents a large possible ornithischian or a sauropod that was originally assigned to Sanpasaurus Liujianpus[19] L. shunan Footprints Sauropodomorph footprints, with features seen in the ichnogenus Otozum, as well as in the sauropod ichnogenus Brontopodus.

Associated Brontopodus-like trackway with Liujianpus indicates that small and large sauropodomorphs may have co-existed.

The narrow-gauge trackway pattern resembles Parabrontopodus, well known from the Jurassic, but other features, such as the low heteropody, are different Sanpasaurus[2] A sauropod with uncertain affinities inside the group.

It was described in the Zigong Museum Guide "Yibinosaurus"[27] An invalid genus of sauropod of uncertain affinities.

The Grallator relationships of these tracks are solid, as they don't display features of other ichnogenera found in the early Jurassic of the same region.

Lower vegetation members Clathropteris[33][34] Yangtze Gorges area Affinities with Dipteridaceae inside Polypodiales.

Here is indicator of Toarcian age for the sedimnets Equisetites[7][36][33][34] Affinities with Equisetaceae inside Equisetales.

Based on analogies with morphologically similar extant Equisetum species, it is interpreted to represent a plant of consistently moist habitats, such as marshes, lake margins or forest understorey, developed normally dense thickets.
