There are additional unidentified conchostraca (clam shrimps, arthropods) on the slab. The age of the Daohugou strata has been notoriously difficult to determine, and a number of studies have produced conflicting results. Gao and Shubin, 2001 reported an Argon-argon dating age of 164 ±4 million years ago (Middle to Late Jurassic, Bathonian to Oxfordian); this opinion is now widely accepted. Taxonomy according to Fossilworks.org. Diagnosis for the family OSMYLIDAE Leach, 1815 according to Winterton et al., 2019 p. 13. “Adult head with dorsal tentorial arms weakly developed; ocelli usually present, medial ocellus sometimes reduced (e.g., Paryphosmylus) or all ocelli completely absent (e.g., Gumillinae); palpimaculae absent; antennae filiform; wings with basal subcostal veinlet simple in costal area, sometimes forked but never recurrent; single basal crossvein (sc-r) between Sc and R, rarely more than one (e.g., Porismus, Archaeosmylidia); Sc and RA fused apically and joining costal margin before wing apex in both wings; single branch of RP, subsequently pectinately branched (5 or more branches); FW radial branches frequently curved posteriorly in apical half of wing, sometimes sinuous; FW medial vein fork variably placed along wing, HW medial vein fork near wing base; FW CuP pectinately (rarely dichotomously) branched; cubital field relatively large in both wings; nygmata typically present; trichosors present in both wings (rarely reduced to apical margin); end twigging along wing margin present, sometimes extensive and multi-layered; jugal lobe present; female gonocoxite 9 (gx 9) (i.e., gonopophysis lateralis) elongate and with terminal stylus; female with a pair of sclerotised spermathecae; male genitalia with well-developed arched gonarcus with paired entoprocesses fused laterally; mediuncus curved; parameres present or absent, sometimes fused into single arched sclerite; larva (Fig. 1) with straight, highly elongate jaws; gular-like sclerite absent; seven Malphigian tubules, of which five arge incorporated into the cryptonephridium; eversible claws present on paired prolegs on last abdominal segment.” Identified by Alex Khramov (Borissiak Paleontological Institute of the Russian Academy of Sciences, Moscow, Russia): “Osmylidae, but definitely not Ponomarenkius or any other Kempyninae. Which genus or subfamily I cannot tell you - too fragmentary preservation and, moreover, there are many undescribed osmylids in Daohugou, so probably your specimen is one of them.” References: Gao K Q, Shubin N.

A fossil sensation: First Hybrid between Odonata and Arachnida!
oilshale posted a topic in Is It Real? How to Recognize Fossil Fabrications
A sensation: First fossil evidence of a hybrid of Odonata and Arachnida from the Middle Jurassic of Daohugou, Inner Mongolia. A talented artist has painted one pair of legs too much by mistake. Was unfortunately sold to a trusting collector.

The age of the Daohugou strata has been notoriously difficult to determine, and a number of studies have produced conflicting results. Gao and Shubin reported an Argon-argon dating age of 164+- 4 million years ago (Middle to Late Jurassic, Bathonian to Oxfordian), this oppinion is now widely accepted. Part and counterpart of the same fossil. There are additional unidentified conchostraca (clam shrimps, arthropods) on the slabs. Drawing of the holotype by Liang et al. 2012 Taxonomy according Fossilworks.org. Differential diagnosis (genus) according to Liang et al, 2012: "The new genus can be distinguished from other representatives of the family by the richly branched Sc. The new genus additionally differs from Liadoblattina Handlirsch, 1906 (Vršanský and Ansorge 2007) from Early Jurassic of Germany and England in having a larger body and reticulations present in the CuA-CuP area. Graciliblatta is also different from Raphidiomima and Cameloblatta in the elongated pronotum (the length-to-width ratio of the pronotum of the new genus is 1.5, those of Raphidiomima and Cameloblatta 1.2), and distinctive divided eyes located basally, which are undivided in the other genera, which originate from the Late Jurassic of Kazakhstan. The head and pronotum of Graciliblatta are extremely long and narrower than in Fortiblatta (Liang et al. 2009); vein R of the forewing is more arcuate and R1 has secondary branching not found in Fortiblatta, which is from the same locality and age as Graciliblatta. In addition, the body is smaller (length/width of head in the new genus is 2.25 vs. 1.9 in Fortiblatta; the pronotal length/width of the new genus is 1.5 vs. 1.2 in Fortiblatta). Coloration in the tip of wings is absent, but Graciliblatta has two dark stripes on pronotum, unlike Fortiblatta." Description (species) according to Liang et al., 2012: "Head and pronotum elongated. Forewing long and narrow. Sc richly branched, with 7–8 branches; R not reaching the tip of margin, slightly curved and basally with dark coloration. CuA and CuP slightly curved. Anal veins with tertiary branches. Diagonal fold present. Hind wing with simple Sc; R1 and Rs differentiated, and R1 secondarily branched." Prognathous and sharp mandibles of the species suggest it was a carnivore. Identified by oilshale. Reference: LIANG, J. H., HUANG, W. L. & REN, D.
