Sweet Chinese Jurassic Fossil Cockroach from NJ Fossil Show
Biotalker posted a topic in General Fossil Discussion
I just posted on some fake fossil insects out of China at a show. It seems only fair that I post on an inexpensive nice find I got at the show from the famous Daohugou site in inner Mongolia in China. They are sold as both positive and negative. Check it out. Just remarkable preservation. -
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; ocell

Taxonomy from Wang et al. 2009. Daouhugounectes primitivus is a predaceous water beetle grub with raptorial forelegs and natatorial mid- and hindlegs. Diagnosis from Wang et al. 2009, p. 653." Head transverse, narrowing anterior of the base; nasale with rounded lateral lobes. Mandible with retinaculum near its middle. Prothoracic tergite somewhat longer than meso- and metathoracic tergites. Legs relatively short; mid- and hindleg distinctly longer than foreleg, their femora, tibiae and tarsi subequal in length, tibae slightly dilated at apex, tarsi roundly dilated anteriorly. Foreleg

While this isn't the type of "bug" I normally collect, this one appealed to me as soon as I saw it on the auction site. Can anyone in our masses give me any help with regards to identification? The seller, who is also a member on here BTW, speculated at the order Neuroptera, but that was followed by a (?). It is Jurassic in age, from the Daohugou lagerstatte of Inner Mongolia. Thanks in advance.

Mecoptera (or scorpionfly) non det. from Nei Mongol, China.

From the album: Invertebrates
Same story as yesterday: My colleague and I wanted to visit a customer near Nincheng in Nei Mongol, China when I saw a drywall made out of grey flag stones. Looked very promising. I could pursuade my colleague (who was driving the car) to take a rest.... Unfortunately I could not tear down the wall - the owner of the drywall didn't like my idea and opposed. I guess the shale is from Daohugou region. Mecoptera non det. Female Possibly belonging to the Panorpidae Jiulongshan Formation Middle Jurassic Ningcheng Nei Mongol China -

Hi, this is a specimen from Daohugou, Liaoning. Is it a Sinaeschnidia cancellosa?

Taxonomy from Gao & Shubin 2003. Identified by Prof Wang Yuan, Institute of Vertebrate Paleontology and Paleoanthropology, Beijing with the following remarks: 'The phalangeal formula for Chunerpeton is variable. This specimen falls in the range as I observed hundreds of specimens of this genus and species. One problem is that, as I noted in the last email, Gao and Shubin (2012) named Beiyanerpeton jianpingensis but it is actually a Chunerpeton by my judgement. The salamander you send to me should be from the same region, but a different quarry as "Beiyanerpeton".' Diagnosis

Taxonomy from Liu et al. 2006. Diagnosis (Liu et al. 2006, p. 550): "Comparing with A. conspecta (Sinitshenkova, 1992),A. yehae sp. nov. exposits more morphological characters of the genus, and is distinct from A. conspecta in the forewings: RS forks almost at the level of the SC tip, rs-m entering the RS before the RS fork and touching M at the M fork, the shorter c-sc and the longer wing."
