Morphology and Developmental Traits of the Trilobite Changaspis Elongata from the Cambrian Series 2 of Guizhou, South China
Morphology and developmental traits of the trilobite Changaspis elongata from the Cambrian Series 2 of Guizhou, South China GUANG-YING DU, JIN PENG, DE-ZHI WANG, QIU-JUN WANG, YI-FAN WANG, and HUI ZHANG Du, G.-Y., Peng, J., Wang, D.-Z., Wang, Q.-J., Wang, Y.-F., and Zhang, H. 2019. Morphology and developmental traits of the trilobite Changaspis elongata from the Cambrian Series 2 of Guizhou, South China. Acta Palaeontologica Polonica 64 (4): 797–813. The morphology and ontogeny of the trilobite Changaspis elongata based on 216 specimens collected from the Lazizhai section of the Balang Formation (Stage 4, Series 2 of the Cambrian) in Guizhou Province, South China are described. The relatively continuous ontogenetic series reveals morphological changes, and shows that the species has seventeen thoracic segments in the holaspid period, instead of the sixteen as previously suggested. The development of the pygid- ial segments shows that their number gradually decreases during ontogeny. A new dataset of well-preserved specimens offers a unique opportunity to investigate developmental traits after segment addition is completed. The ontogenetic size progressions for the lengths of cephalon and trunk show overall compliance with Dyar’s rule. As a result of different average growth rates for the lengths of cephalon, trunk and pygidium, the length of the thorax relative to the body shows a gradually increasing trend; however, the cephalon and pygidium follow the opposite trend. Morphometric analysis across fourteen post-embryonic stages reveals growth gradients with increasing values for each thoracic segment from anterior to posterior. The reconstruction of the development traits shows visualization of the changes in relative growth and segmentation for the different body parts. -

Unit-V Evolution of Horse
UNIT-V EVOLUTION OF HORSE Horses (Equus) are odd-toed hooped mammals belong- ing to the order Perissodactyla. Horse evolution is a straight line evolution and is a suitable example for orthogenesis. It started from Eocene period. The entire evolutionary sequence of horse history is recorded in North America. " Place of Origin The place of origin of horse is North America. From here, horses migrated to Europe and Asia. By the end of Pleis- tocene period, horses became extinct in the motherland (N. America). The horses now living in N. America are the de- scendants of migrants from other continents. Time of Origin The horse evolution started some 58 million years ago, m the beginning of Eocene period of Coenozoic era. The modem horse Equus originated in Pleistocene period about 2 million years ago. Evolutionary Trends The fossils of horses that lived in different periods, show that the body parts exhibited progressive changes towards a particular direction. These directional changes are called evo- lutionary trends. The evolutionary trends of horse evolution are summarized below: 1. Increase in size. 2. Increase in the length of limbs. 3. Increase in the length of the neck. 4. Increase in the length of preorbital region (face). 5. Increase in the length and size of III digit. 6. Increase in the size and complexity of brain. 7. Molarization of premolars. Olfactory bulb Hyracotherium Mesohippus Equus Fig.: Evolution of brain in horse. 8. Development of high crowns in premolars and molars. 9. Change of plantigrade gait to unguligrade gait. 10. Formation of diastema. 11. Disappearance of lateral digits. -

Brisbane. ISSN0079-8835. Aconsolidated list of available generic names introduced since the beginning of the binomial nomenclature system for trilobites is presented for the first time. Each entry is accompanied by the author and date of availability, by the name of the type species, by a lithostratigraphic or biostratigraphic and geographic reference for the type species, by a family assignment and by an age indication of the type species at the Period level (e.g. MCAM, LDEV). A second listing of these names is taxonomically arranged in families with the families listed alphabetically, higher level classification being outside the scope of this work. We also provide a list of names that have apparently been applied to trilobites but which remain nomina nuda within the ICZN definition. Peter A.

Perinate and Eggs of a Giant Caenagnathid Dinosaur from the Late Cretaceous of Central China
ARTICLE Received 29 Jul 2016 | Accepted 15 Feb 2017 | Published 9 May 2017 DOI: 10.1038/ncomms14952 OPEN Perinate and eggs of a giant caenagnathid dinosaur from the Late Cretaceous of central China Hanyong Pu1, Darla K. Zelenitsky2, Junchang Lu¨3, Philip J. Currie4, Kenneth Carpenter5,LiXu1, Eva B. Koppelhus4, Songhai Jia1, Le Xiao1, Huali Chuang1, Tianran Li1, Martin Kundra´t6 & Caizhi Shen3 The abundance of dinosaur eggs in Upper Cretaceous strata of Henan Province, China led to the collection and export of countless such fossils. One of these specimens, recently repatriated to China, is a partial clutch of large dinosaur eggs (Macroelongatoolithus) with a closely associated small theropod skeleton. Here we identify the specimen as an embryo and eggs of a new, large caenagnathid oviraptorosaur, Beibeilong sinensis. This specimen is the first known association between skeletal remains and eggs of caenagnathids. Caenagnathids and oviraptorids share similarities in their eggs and clutches, although the eggs of Beibeilong are significantly larger than those of oviraptorids and indicate an adult body size comparable to a gigantic caenagnathid. An abundance of Macroelongatoolithus eggs reported from Asia and North America contrasts with the dearth of giant caenagnathid skeletal remains. Regardless, the large caenagnathid-Macroelongatoolithus association revealed here suggests these dinosaurs were relatively common during the early Late Cretaceous. 1 Henan Geological Museum, Zhengzhou 450016, China. 2 Department of Geoscience, University of Calgary, Calgary, Alberta, Canada T2N 1N4. 3 Institute of Geology, Chinese Academy of Geological Sciences, Beijing 100037, China. 4 Department of Biological Sciences, University of Alberta, Edmonton, Alberta, Canada T6G 2E9. 5 Prehistoric Museum, Utah State University, 155 East Main Street, Price, Utah 84501, USA.
