New Discovery

A new fossil salamander,Nuominerpeton aquilonaris(gen. et sp. nov.), is named and described based on specimens from the Lower Cretaceous Guanghua Formation of Inner Mongolia, China. The new discovery documents a far northern occurrence of Early Cretaceous salamanders in China, extending the geographic distribution for the Mesozoic fossil record of the group from the Jehol area (40th–45th parallel north) to near the 49th parallel north. The new salamander is characterized by having the orbitosphenoid semicircular in shape; coracoid plate of the scapulocoracoid greatly expanded with a convex ventral and posterior border; ossification of two centralia in carpus and tarsus; and first digit being about half the length of the second digit in both manus and pes. The new salamander appears to be closely related to hynobiids, although this inferred relationship awaits confirmation by research in progress by us on a morphological and molecular combined analysis of cryptobranchoid relationships. Comparison of adult with larval and postmetamorphic juvenile specimens provides insights into developmental patterns of cranial and postcranial skeletons in this fossil species, especially resorption of the palatine and anterior portions of the palatopterygoid in the palate and the coronoid in the mandible during metamorphosis, and postmetamorphic ossification of the mesopodium in both manus and pes. Thus, this study provides a rare case study of developmental features in a Mesozoic salamander.

Small Family

Hybosoridae is a relatively small family of Scarabaeoidea, including five extant and one fossil subfamily (Ocampo & Ballerio 2006, Nikolajev 2007). Until now, 20 fossil species were known from five subfamilies: Anaidinae, Ceratocanthinae, Hybosorinae, Liparochrinae, and Mimaphodiinae (Ocampo & Ballerio 2006, Krell 2007, Nikolajev 2008, Nikolajev et al. 2010, Nikolajev 2010a, Nikolajev 2010b, Kirejtshuk et al. 2011). In this paper we describe Pulcherhybosorus tridentatus Yan, Bai, & Ren new genus and new species, from a nearly complete and well-preserved fossil. This fossil represents the first record of Hybosoridae from the Early Cretaceous Yixian Formation of Liutiaogou, Inner Mongolia in China. This significant finding tentatively confirms the presence of Hybosoridae during the Mesozoic in what is now China.

Crane Flies

Trichoceridae, species of which are commonly known as winter crane flies, is a rather small family that includes 79 fossil species and ca. 160 extant ones (Krzemińska et al., 2009; Dong et al., 2014). Among them, 10 species have been described from the Middle-Upper Jurassic Haifanggou Formation at Daohugou, Ningcheng County, Inner Mongolia, North China (Zhang, 2006; Krzemińska et al., 2009; Liu et al., 2012; Dong et al., 2014). The subgenus Archaeotrichocera of Eotrichocera contains seven species, described mainly from the Middle–Late Jurassic Daohugou biota of China (Zhang, 2006; Krzemińska et al., 2009; Dong et al., 2014) with one species found from the Early Cretaceous of Kempendyay in Yakutia, Russia (Krzemińska et al., 2009).

Chapada Do Araripe

Abstract Mantodea are very rare in the fossil record. 28 fossil species are reported since the earliest occurrence of mantodeans in the Upper Jurassic (Tithonian). Here, I describe Cretophotina santanensis n. sp. from the Aptian (Lower Cretaceous) Crato Formation of Chapada do Araripe (northeastern Brazil). This species is characterized by long antenna and primitive raptorial forelegs. Morphological characters shared with the living genus Chaeteessa would support its assignment to the family Chaeteessidae. The tropical occurrence of the Early Cretaceous genus Cretophotina in Gondwana, together with occurrences of the genus Chaetessa from subtropical and temperate zones of Laurasia, implies that members of the family Chaeteessidae achieved nearly cosmopolitan distribution during the Early Cretaceous.

A New Species

AbstractThe fossil record of the clawed lobster genus,Homarus, is appraised. The taxonomic history ofHomarusandHoplopariais summarized, and a list of species recognized for each is provided. A tabulation of all fossil species of the family Nephropidae permits assessment of nephropid species diversity through time. A new species ofHomarus,H.hungaricus, is recorded from the upper Oligocene (Chattian) Mány Formation at Mány, northern Hungary. The species is known by a single specimen consisting of a partial cephalothorax, a pleon minus telson, and partial chelipeds.Homarusis now known by two extant species (H.americanusandH.gammarus) and six fossil taxa, one of Early Cretaceous (Albian;H.benedeni) and five of Cenozoic age (H.hungaricusn. sp.,H.klebsi,H.lehmanni,H.morrisi, andH.percyi). The new fossilHomarusdiffers from modern congeners in aspects of carapace and pleon ornamentation and, especially, cutter claw shape. This is the fourth Oligocene occurrence of a nephropid species; all areHomarusand all are from Western Europe.Homarusmakes its appearance in the fossil record in the Early Cretaceous (Albian) and then is not known again until the Paleogene, despite the fact that nephropid lobsters in general are well known from the Late Cretaceous. Nephropid lobsters are better known from the Cretaceous than from the Cenozoic. Both raw species numbers and numbers corrected (normalized) for epicontinental sea coverage show that shelf-dwelling nephropid lobsters were most diverse during the Late Cretaceous.

AbstractFirst record of the genus Helius—long-rostrum cranefly from Maestrazgo Basin (eastern Spain, Iberian Penisula) is documented. Two new fossil species of the genus Helius are described from Cretaceous Spanish amber and compared with other species of the genus known from fossil record with particular references to these known from Cretaceous period. Helius turolensis sp. nov. is described from San Just amber (Lower Cretaceous, upper Albian) Maestrazgo Basin, eastern Spain, and Helius hispanicus sp. nov. is described from Álava amber (Lower Cretaceous, upper Albian), Basque-Cantabrian Basin, northern Spain. The specific body morphology of representatives of the genus Helius preserved in Spanish amber was discussed in relation to the environmental conditions of the Maestrazgo Basin and Basque-Cantabrian Basin in Cretaceous.

Long Term Trends

Ecosystem services management should often expect to deal with non-linearities due to trade-offs and synergies between ecosystem services (ES). Therefore, it is important to analyze long-term trends in ES development and utilization to understand their responses to climate change and intensification of human activities. In this paper, the region of Uxin in Inner Mongolia, China, was chosen as a case study area to describe the spatial distribution and trends of 5 ES indicators. Changes in relationships between ES and driving forces of dynamics of ES relationships were analyzed for the period 1979–2016 using a stepwise regression. We found that: the magnitude and directions in ES relationships changed during this extended period; those changes are influenced by climate factors, land use change, technological progress, and population growth.
