Taxonomy from Fossilworks.com. Etymology: “Jehol,” refers to “the Jehol Biota”; “chelys” is “turtle” in Greek; the specific epithet refers to the type locality. Diagnosis from Shao et al. 2018, p. 7/21: "This new taxon has a low-domed shell, as in other Cretaceous sinemydids, and it is diagnosted with an unusual combination of features: nasal absent; midline contact of prefrontals; interorbital roof narrow; parietal expanded bilaterally along the supraoccipital crest; parietal separated from squamosal; supraoccipital crest slightly longer than squamosal horn; upper temporal emargination moderately developed; cranial scales present; oval carapace distinctly longer than wide; nuchal emargination shallow; preneural absent; eight neurals; two subequal suprapygals; pygal present; third costals with parallel anterior and posterior sides; cervical scale present; vertebral scales wider than long; first vertebral wider than nuchal and contact second marginal; central and posterior plastral fenestrae absent; lateral plastral fenestrae large; four phalanges of pedal digit V."

Unidentified plant from Jiufotang Formation of Sihedang, Lingyuan, Liaoning
-Andy- posted a topic in Fossil ID
Hello, I have an unidentified plant from the Jiufotang Formation of Sihedang, Lingyuan, Liaoning Province I acquired this plant as a Baiera sp. However, due to the way it was preserved, I cannot tell if it has the characteristic "split-vein" lobes of Ginkgoales. Also problematic is that Baiera sp. from Jiufotang seem to come in a wide variety of shapes Here are two pics of Baiera sp. from China. There is also a paywalled article A new species of Baiera from the Early Cretaceous Jehol Biota of southeastern Jilin, China so I'd appreciate if anyone can share info from it Anyway, there is also Liaoningocladus boii from the Jehol Biota which is a close match for my plant What do you guys think? If you suspect it's another plant genus, please feel free to tell me. Thank you -
