Dinosaurs & Fossils of Lesotho helplesotho.org Lesotho is home to numerous plant and animal fossils, as well as dinosaur fossils. The majority of the earliest fossils discovered were found by missionaries who explored the land. Lesotho has one of the largest concentrations of dinosaur footprints in the world. Lesotho has numerous footprint locations with sites at Morija, Subeng Stream and Tsikoane, Moyenu, Matsieng, and Mohale’s Hoek. The Dinosaur of Lesotho: The Lesothosaurus! Peter M. Galton discovered the fossils of an unknown dinosaur in 1978. The Lesothosaurus lived in the early Jurassic period, approximately 200 million years ago. The Lesothosaurus was one of the earliest ornithischians, or “bird- hipped” dinosaurs. The Lesothosaurus was a small and lightly built dinosaur. It was about 1 m long and would have come up to the thigh of a 2 m person. The dinosaur was lizard-like in that it Image © National Geographic Society walked on two long legs and had feet with four toes. It had short arms with hands with five fingers, a flexible neck and a small head. The tail was about 3 feet long. They were herbivores and had teeth designed for shredding plants. It is believed that the Lesothosaurus died out in the mid-Jurassic period. Other members of the ornithischians species lived for another 150 million years until the extinction of dinosaurs. Other dinosaur fossils found in Lesotho included those of the Massospondylus and Heterodontosaurus.

A Neoceratopsian Dinosaur from the Early Cretaceous of Mongolia And
ARTICLE https://doi.org/10.1038/s42003-020-01222-7 OPEN A neoceratopsian dinosaur from the early Cretaceous of Mongolia and the early evolution of ceratopsia ✉ Congyu Yu 1 , Albert Prieto-Marquez2, Tsogtbaatar Chinzorig 3,4, Zorigt Badamkhatan4,5 & Mark Norell1 1234567890():,; Ceratopsia is a diverse dinosaur clade from the Middle Jurassic to Late Cretaceous with early diversification in East Asia. However, the phylogeny of basal ceratopsians remains unclear. Here we report a new basal neoceratopsian dinosaur Beg tse based on a partial skull from Baruunbayan, Ömnögovi aimag, Mongolia. Beg is diagnosed by a unique combination of primitive and derived characters including a primitively deep premaxilla with four pre- maxillary teeth, a trapezoidal antorbital fossa with a poorly delineated anterior margin, very short dentary with an expanded and shallow groove on lateral surface, the derived presence of a robust jugal having a foramen on its anteromedial surface, and five equally spaced tubercles on the lateral ridge of the surangular. This is to our knowledge the earliest known occurrence of basal neoceratopsian in Mongolia, where this group was previously only known from Late Cretaceous strata. Phylogenetic analysis indicates that it is sister to all other neoceratopsian dinosaurs. 1 Division of Vertebrate Paleontology, American Museum of Natural History, New York 10024, USA. 2 Institut Català de Paleontologia Miquel Crusafont, ICTA-ICP, Edifici Z, c/de les Columnes s/n Campus de la Universitat Autònoma de Barcelona, 08193 Cerdanyola del Vallès Sabadell, Barcelona, Spain. 3 Department of Biological Sciences, North Carolina State University, Raleigh, NC 27695, USA. 4 Institute of Paleontology, Mongolian Academy of Sciences, ✉ Ulaanbaatar 15160, Mongolia.

We conclude that these fossil remains represent a bipedal heterodontosaurid but lack diagnostic characters to identify them at the species level, although they probably represent remains of Manidens condorensis, known from the same locality. Histological features suggest a subadult ontogenetic stage for the individual. A cluster analysis based on pedal measurements identiﬁes similarities of this specimen with heterodontosaurid taxa and the inclusion of the new material in a phylogenetic analysis with expanded character sampling on pedal remains conﬁrms the described specimen as a heterodontosaurid. Finally, uncommon features of the digits (length proportions among nonungual phalanges of digit III, and claw features) are also quantitatively compared to several ornithischians, theropods, and birds, suggesting that this may represent a bipedal cursorial heterodontosaurid with gracile and grasping feet and long digits.

A Phylogenetic Analysis of the Basal Ornithischia (Reptilia, Dinosauria)
A PHYLOGENETIC ANALYSIS OF THE BASAL ORNITHISCHIA (REPTILIA, DINOSAURIA) Marc Richard Spencer A Thesis Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements of the degree of MASTER OF SCIENCE December 2007 Committee: Margaret M. Yacobucci, Advisor Don C. Steinker Daniel M. Pavuk © 2007 Marc Richard Spencer All Rights Reserved iii ABSTRACT Margaret M. Yacobucci, Advisor The placement of Lesothosaurus diagnosticus and the Heterodontosauridae within the Ornithischia has been problematic. Historically, Lesothosaurus has been regarded as a basal ornithischian dinosaur, the sister taxon to the Genasauria. Recent phylogenetic analyses, however, have placed Lesothosaurus as a more derived ornithischian within the Genasauria. The Fabrosauridae, of which Lesothosaurus was considered a member, has never been phylogenetically corroborated and has been considered a paraphyletic assemblage. Prior to recent phylogenetic analyses, the problematic Heterodontosauridae was placed within the Ornithopoda as the sister taxon to the Euornithopoda. The heterodontosaurids have also been considered as the basal member of the Cerapoda (Ornithopoda + Marginocephalia), the sister taxon to the Marginocephalia, and as the sister taxon to the Genasauria. To reevaluate the placement of these taxa, along with other basal ornithischians and more derived subclades, a phylogenetic analysis of 19 taxonomic units, including two outgroup taxa, was performed. Analysis of 97 characters and their associated character states culled, modified, and/or rescored from published literature based on published descriptions, produced four most parsimonious trees. Consistency and retention indices were calculated and a bootstrap analysis was performed to determine the relative support for the resultant phylogeny. The Ornithischia was recovered with Pisanosaurus as its basalmost member.

A Revision of the Upper Triassic Ornithischian Dinosaur Revueltosaurus, with a Description of a New Species
Heckert, A.B" and Lucas, S.O., eds., 2002, Upper Triassic Stratigraphy and Paleontology. New Mexico Museum of Natural History & Science Bulletin No.2 J. 253 A REVISION OF THE UPPER TRIASSIC ORNITHISCHIAN DINOSAUR REVUELTOSAURUS, WITH A DESCRIPTION OF A NEW SPECIES ANDREW B. HECKERT New Mexico Museum of Natural History, 1801 Mountain Road NW, Albuquerque, NM 87104-1375 Abstract-Ornithischian dinosaur body fossils are extremely rare in Triassic rocks worldwide, and to date the majority of such fossils consist of isolated teeth. Revueltosaurus is the most common Upper Triassic ornithischian dinosaur and is known from Chinle Group strata in New Mexico and Arizona. Historically, all large (>1 cm tall) and many small ornithischian dinosaur teeth from the Chinle have been referred to the type species, Revueltosaurus callenderi Hunt. A careful re-examination of the type and referred material of Revueltosaurus callenderi reveals that: (1) R. callenderi is a valid taxon, in spite of cladistic arguments to the contrary; (2) many teeth previously referred to R. callenderi, particularly from the Placerias quarry, instead represent other, more basal, ornithischians; and (3) teeth from the vicinity of St. Johns, Arizona, and Lamy, New Mexico previously referred to R. callenderi pertain to a new spe cies, named Revueltosaurus hunti here. R. hunti is more derived than R. callenderi and is one of the most derived Triassic ornithischians. However, detailed biostratigraphy indicates that R. hunti is older (Adamanian: latest Carnian) than R. callenderi (Revueltian: early-mid Norian). Both taxa have great potential as index taxa of their respective faunachrons and support existing biochronologies based on other tetrapods, megafossil plants, palynostratigraphy, and lithostratigraphy.

Taphonomy As an Aid to African Palaeontology*
Palaeont. afr., 24 (1981 ) PRESIDENTIAL ADDRESS: TAPHONOMY AS AN AID TO AFRICAN PALAEONTOLOGY* by C.K. Brain Transvaal Museum, P.O. Box 413, Pretoria 0001 SUMMARY Palaeontology has its roots in both the earth and life sciences. Its usefulness to geology comes from the light which the understanding of fossils may throw on the stratigraphic re lationships of sediments, or the presence of economic deposits such as coal or oil. In biology, the study of fossils has the same objectives as does the study of living animals or plants and such objectives are generally reached in a series of steps which may be set out as follows: STEP I. Discovering what forms of life are, or were, to be found in a particular place at a particular time. Each form is allocated a name and is fitted into a system of classification. These contributions are made by the taxonomist or the systematist. STEP 2. Gaining afuller understanding ofeach described taxon as a living entity. Here the input is from the anatomist, developmental biologist, genetIcIst, physi ologist or ethologist and the information gained is likely to modify earlier decisions taken on the systematic position of the forms involved. STEP 3. Understanding the position ofeach form in the living community or ecosystem. This step is usually taken by a population biologist or ecologist. Hopefully, any competent neo- or palaeobiologist (I use the latter term deliberately in this context in preference to "palaeontologist") should be able to contribute to more than one of the steps outlined above. Although the taxonomic and systematic steps have traditionally been taken in museums or related institutions, it is encouraging to see that some of the steps subsequent to these very basic classificatory ones are now also being taken by museum biol ogists.

ARTICLE doi:10.1038/nature21700 A new hypothesis of dinosaur relationships and early dinosaur evolution Matthew G. Baron1,2, David B. Norman1 & Paul M. Barrett2 For 130 years, dinosaurs have been divided into two distinct clades—Ornithischia and Saurischia. Here we present a hypothesis for the phylogenetic relationships of the major dinosaurian groups that challenges the current consensus concerning early dinosaur evolution and highlights problematic aspects of current cladistic definitions. Our study has found a sister-group relationship between Ornithischia and Theropoda (united in the new clade Ornithoscelida), with Sauropodomorpha and Herrerasauridae (as the redefined Saurischia) forming its monophyletic outgroup. This new tree topology requires redefinition and rediagnosis of Dinosauria and the subsidiary dinosaurian clades. In addition, it forces re-evaluations of early dinosaur cladogenesis and character evolution, suggests that hypercarnivory was acquired independently in herrerasaurids and theropods, and offers an explanation for many of the anatomical features previously regarded as notable convergences between theropods and early ornithischians.
