Anatomical Structures of Microsporangiate Cone of Lepidodendrales-- Lepidos trobus Shanxiense sp. nov.

A new anatomically-preserved microsporangiate cone in the coal balls of Coal Seam No. 7 (P1′) at the upper part of Taiyuan Formation in Xishan Coal-Field, Taiyuan, Shanxi Province of China was described. Having been studied, it was placed into Lepidostrobus Brongniart and considered as a new species. Vegetative organs of Lepidodendrales from mainly belonged to the natural genus Lepidodendron, such as stems, leaves and roots in the coal balls were visualized. However a few of them probably belonged to the natural genus Sigillaria. Besides, the single megasporophylls with megasporangia of Achlarnydocarpon (the megasporangiate cone of Lep/dodendron) have been found in the coal balls, so the specimens under discussion might belong to Lepidodendron. Lepidostrobus shanxiense sp. nov. The cone more than 3.5 cm long and 1.6～ 1.8 cm in width. The axis possesses siphonostele. The sporophylls on the axis in spiral arrangement. The pedicel 6～ 7 mm long and the distal lamina more than 1.2 cm long. The pedicel alate with alations extending about 2 ～ 2. 5 mm outward. The microsporangium probably bag-shaped, equal to the pedicel in length, 4.5 mm wide and 2～ 3 mm high, attached to the pedicel for about 2/3 of its length. The wall one cell thick in fully matured microsporan gia and consists of uniform columnar cells. The microspore 68～77μm in diameter, trilete and the surface minutely granular.

The specimens were collected from the upper Triassic coal series of Liuzhi district, Guizhou province. Main characters of the new species: Leaf bipinnate, ultimate pinna lanceolate, pinnules drepaniform, entire, apex obtuse, pinnules arising from the upper side of pinna rachis. Cuticles rather thick. Stomatal apparatus haplocheilic, smaller, confined to the lower epidermis, scattered in the areas between veins, variably orientated, 70–80 per sq. mm.     

The earliest fossil record of Panorpidae (Mecoptera) from the Middle Jurassic of China

The early history of Panorpidae (Mecoptera) is poorly known due to sparse fossil records. Up to date, only nine fossil species have been described, all from the Paleogene, except the Early Cretaceous Solusipanorpa gibbidorsa Lin, 1980. However, we suggest S. gibbidorsa is too incompletely preserved to permit even family classification. A new genus with two new species, Jurassipanorpa impunctata gen. et sp. n. and Jurassipanorpa sticta sp. n., are described based on four well-preserved specimens from the late Middle Jurassic Jiulongshan Formation of Daohugou, Inner Mongolia, China. These two new species are the earliest fossil records of Panorpidae. The new genus is erected based on a combination of forewing characters: both R₁ and Rs₁ with two branches, 1A reaching posterior margin of wing distad of the forking of Rs from R_1, and no crossveins or only one crossvein between veins of 1A and 2A. In all four specimens, long and robust setae ranging from 0.09 to 0.38 mm in length and pointing anteriorly, are present on anal veins of forewings. The function of these setae is enigmatic.

Osmunda (Osmundaceae) from the Triassic of Antarctica: an example of evolutionary stasis

Compressed specimens of the fern Osmunda are described from the Triassic of the Allan Hills, Antarctica. The specimens consist of a once pinnate, deeply pinnatifid fertile frond as well as several sterile specimens. Six pinnae are present on the partial fertile rachis, with two sterile pinnae above four fertile pinnae. Both sterile and fertile specimens are virtually identical to the modern species Osmunda claytoniana. Entire fronds are fragmentary; the longest is 21 cm in length. Sterile pinnae are alternate and deeply pinnatifid, with slightly toothed pinnules and dichotomous venation. Fertile pinnae are 1-1.3 cm long, once pinnate, and lack vegetative lamina. Sporangia are clustered, each 300-375 um in diameter, and possess a transverse annulus 6-8 cells long; dehiscence is by a vertical slit. Fronds arise from a rhizome 4 cm long by 1 cm wide; two croziers are present on the rhizome. Two frond segments up to 6 cm long and three deeply pinnatifid pinnae are present on the uppermost part of one rachis. Pinnules are ~4 mm long and 2-3 mm wide. The presence of this Osmunda species in the Triassic demonstrates stasis of frond morphology, both fertile and vegetative, for the genus.

A new pearleye (Teleostei,Aulopiformes) species from the Oligocene of Romania

A new pearleye species of the alepisauroid family Scopelarchidae, Scopelarchoides neamticus sp. nov., is described herein based on two specimens from the Oligocene Lower Dysodilic Shales Formation, cropping out in the Pietricica Mountain, Romanian Eastern Carpathians. The new species described herein exhibits a unique combination of features (including head length about 25% of SL; coracoid remarkably expanded; both preorbital and postorbital lengths larger than orbit diameter; 50 or 51 vertebrae; dorsal fin with nine or ten rays; anal-fin with 28 rays; length of anal fin base about 30% of SL; preanal distance almost 60% of SL; pelvic fin insertion located just under the second dorsal fin ray; pectoral fins only slightly longer than pelvic fins; caudal fin with 19 principal rays plus 14 upper and 13 lower procurrent rays) that justifies its recognition as a new species of the genus Scopelarchoides. Both morphological and meristic features suggest a certain degree of similarity between S. neamticus sp. nov. and the extant species Scopelarchoides signifer. The fossils of the new Oligocene species described herein represent the oldest known skeletal record of Scopelarchidae.
