Taxonomy from Fossilworks.org. Diagnosis from Knobloch 1998, p. 81: "Leaves imparipinnate with seven leaflets, the terminal leaflets up to 8.2 x 2.4 cm, the lateral leaflets reach sizes up to 6 x 2.2 or 6.6 x 1.4 cm. The leaflets are narrowly elliptic or oblong-lanceolate, adnate to the rachis without petioles, gradually tapering to a rather long point, their base is wedge-shaped or rounded-wedge-shaped, the margin is distantly serrate, the teeth are abuttingly directed forward, the incisions sharp. The secondary nerve is distinctly weak, not very pronounced and hardly visible. The arcuate secondary nerves bifurcate just before the leaf margin and branch from the straight median nerve at obtuse angles, one secondary nerve can innervate one tooth as well as two teeth, sometimes intermediate nerves occur. The tertiary nerves form a very loose, large-meshed network (no anastomoses between two secondary nerves."

“Parrotia” pristina (Ettingshausen 1851) Stur 1867 with feeding traces.
oilshale posted a fossil in Plants
Taxonomy from GBIF.org. There is a complex literature about this polymorphic species. Similar leaf shapes possess the recent genera Hamamelis L., Fothergilla L., and Parrotia C.A. Meyer, therefore the term "Parrotia" pristina (Ettingshausen) Stur is used. Quote from B. Adroit 2020, p. 4 regarding the feeding traces: ”Currently, the main reference to identify and classify the plant–insect interactions in the fossil record is the ‘Guide to Insect (and Other) Damage Types on Compressed Plant Fossils’. This guide subdivides herbivory traces on leaves into seven functional feeding groups (FFGs): hole feeding, margin feeding, skeletonization, surface feeding, mining, piercing and sucking and galling.” This type of feeding trace was assigned to the damage type DT297. Identified by Dr. B. Androit, Swedish Museum of Natural History. References: Stur, D. (1867).

Sciara willershausensis together with the much smaller and much more common Sciara strausi. Taxonomy according to Kohring & Schlüter 1993. Morphology according to Kohring and Schlüter, 1993, p. 193 (translated from German by oilshale): “The body length is about 7.2 mm. The wing length is between 4.8 and 5.2 mm. The head is very small. The antennae are only incompletely preserved, in total the antennae are on average 1.5 mm long. Individual antennae are indistinctly recognizable in outline. The thorax is 2,1 mm long and oval shaped. The abdomen is 4.5 mm long and evenly pointed. The wing is round curved. Sc and R1 stands out clearly due to dark coloration. Pedicel of m-fork only slightly longer than branches M1 and M2. Cu with very short pedicel, branches distinctly longer..." Line drawing of the forewing from Kohring & Schlüter 1993, p. 192: Identified by oilshale using Kohring & Schlüter 1993. Reference.: Kohring, R & Schlüter, T. (1993): Sciariden (Insecta: Diptera: Nematocera) aus dem Oberpliozän von Willershausen. Berliner geowissenschaftliche Abhandlungen (E), 9, p. 191-199; Berlin

From Wikipedia: " Small, floating aquatics with creeping stems, branched, bearing hairs on the leaf surface papillae but no true roots. Leaves are in trimerous whorls, with two leaves green, sessile or short-petioled, flat, entire and floating, and one leaf finely dissected, petiolate, rootlike and pendent. Submerged leaves bearing sori that are surrounded by basifixed membranous indusia (sporocarps). "

Agriopis leucophaearia foss. ([DENIS & SCHIFFERMÜLLER], 1775) Forewing Upper Pliocene Willershausen am Harz Germany The determination may be a bit shaky, but in my opinion size and weakly recognizable color pattern fit well to that of the recent form Agriopis leucophaearia ([DENIS & SCHIFFERMÜLLER], 1775). For comparison a picture from Lepiforum.de: -
Together with several small fungus gnats (Sciara strausi Kohring & Schlüter, 1993).
