Here we provide a detailed comparison of the anatomy of Ambiortus relative to other known Early Cretaceous ornithuromorphs from the Chinese Jehol Group and Xiagou Formation. We include new information on Ambiortus from a previously undescribed slab preserving part of the sternum. Ambiortus is superficially similar to Gansus yumenensis from the Aptian Xiagou Forma tion but shares more morphological features with Yixianornis grabaui (Ornithuromorpha: Songlingorni thidae) from the Jiufotang Formation of the Jehol Group. In general, the mosaic pattern of character distri bution among early ornithuromorph taxa does not reveal obvious relationships between taxa. Ambiortus was placed in a large phylogenetic analysis of Mesozoic birds, which confirms morphological observations and places Ambiortus in a polytomy with Yixianornis and Gansus.

The Palaeontological Association 63rd Annual Meeting 15th–21st December 2019 University of Valencia, Spain PROGRAMME ABSTRACTS AGM papers Palaeontological Association 6 ANNUAL MEETING ANNUAL MEETING Palaeontological Association 1 The Palaeontological Association 63rd Annual Meeting 15th–21st December 2019 University of Valencia The programme and abstracts for the 63rd Annual Meeting of the Palaeontological Association are provided after the following information and summary of the meeting. An easy-to-navigate pocket guide to the Meeting is also available to delegates. Venue The Annual Meeting will take place in the faculties of Philosophy and Philology on the Blasco Ibañez Campus of the University of Valencia. The Symposium will take place in the Salon Actos Manuel Sanchis Guarner in the Faculty of Philology. The main meeting will take place in this and a nearby lecture theatre (Salon Actos, Faculty of Philosophy). There is a Metro stop just a few metres from the campus that connects with the centre of the city in 5-10 minutes (Line 3-Facultats). Alternatively, the campus is a 20-25 minute walk from the ‘old town’. Registration Registration will be possible before and during the Symposium at the entrance to the Salon Actos in the Faculty of Philosophy. During the main meeting the registration desk will continue to be available in the Faculty of Philosophy. Oral Presentations All speakers (apart from the symposium speakers) have been allocated 15 minutes. It is therefore expected that you prepare to speak for no more than 12 minutes to allow time for questions and switching between presenters. We have a number of parallel sessions in nearby lecture theatres so timing will be especially important. -

Bird Observer
Bird Observer VOLUME 39, NUMBER 2 APRIL 2011 HOT BIRDS On November 20 the Hampshire Bird Club was waiting at Quabbin headquarters for the rest of the group to arrive when Larry Therrien spotted a flock of 19 swans in the distance— Tundra Swans! Ian Davies took this photograph (left). Since 2003 Cave Swallows have been a specialty of November, showing up in coastal locations in increasing numbers over the years. This year there was a flurry of reports along the New England coast. On Thanksgiving Day, Margo Goetschkes took this photograph (right) of one of the birds at Salisbury. On November 30, Vern Laux got a call from a contractor reporting a “funny bird” at the Nantucket dump. Vern hustled over and was rewarded with great views of this Fork-tailed Flycatcher (left). Imagine: you’re photographing a Rough- legged Hawk in flight, and all of a sudden it is being mobbed—by a Northern Lapwing (right)! That’s what happened to Jim Hully on December 2 on Plum Island. This is only the second state record for this species, the first being in Chilmark in December of 1996. On April 9, Keelin Miller found an interesting gull at Kalmus Beach in Hyannis. As photographs were circulated, opinions shifted toward a Yellow-legged Gull (left). Check out Jeremiah Trimble’s photo from April 13.

The status of CASG 71892 as the oldest known record of either of the two spp. of Uria was recently confirmed by the review of Watanabe et al. (2016). The younger of the two marine transgressions at the Tolstoi Point corresponds to the Bigbendian transgression (Olson, 2013), which contains the Gauss-Matuyama magnetostratigraphic boundary (Kaufman and Brigham-Grette, 1993). Attempts to date this reversal have been recently reviewed by Ohno et al. (2012); Singer (2014), and Head (2019). In particular, Deino et al. (2006) were able to tightly bracket the age of the reversal using high-precision 40Ar/39Ar dating of two tuffs in normally and reversely magnetized lacustrine sediments from Kenya, obtaining a value of 2.589 ± 0.003 Ma. -

A Loon Leg (Aves, Gaviidae) with Crocodilian Tooth from the Late Oligocene of Germany
A Loon Leg (Aves, Gaviidae) with Crocodilian Tooth from the Late Oligocene of Germany GERALD MAYR1* AND MARKUS POSCHMANN2 1Forschungsinstitut Senckenberg, Sektion Ornithologie, Senckenberganlage 25, D-60325 Frankfurt am Main, Germany 2Generaldirektion Kulturelles Erbe RLP, Direktion Landesarchäologie, Referat Erdgeschichte, Große Langgasse 29, D-55116 Mainz, Germany *Corresponding author; E-mail: [email protected] Abstract.—The first late Oligocene fossil record of a loon (Gaviiformes) is described from the lacustrine depos- its of the German locality Enspel. The specimen is an isolated foot, which is associated with a crocodilian tooth. The fossil belongs to a species about half the size of the smallest extant loon, and is morphologically most similar to the Paleogene taxon Colymboides. In all probability it constitutes the prey remains of a crocodilian, which is of particular significance because the distribution ranges of loons and crocodilians hardly overlap today. The Enspel palaeocli- mate was warm-temperate and subtropical, and the Enspel specimen and other Paleogene fossils of gaviiform birds raise the, as yet, unanswered question of why loons largely disappeared from inland habitats of the warmer regions. Received 22 July 2008, accepted 30 December 2008. Key words.—Colymboides, crocodilian tooth, fossil waterbirds, Gaviiformes, palaeoecology.

The Fossil Remains of a Species of Hesperornis Found in Montana
290 SHUFELDT,Remains of Hesperornis. [July[ Auk THE FOSSIL REMAINS OF A SPECIES OF HESPERORNIS FOUND IN MONTANA. BY R. W. SHUFELD% M.D. Plate XI7III. ExR•,¾ in November, 1914, Mr. Charles W. Gihnore, who has chargeof the fossilbirds and reptiles in the Divisionof Palmontology of the United States National Museum, Washington, D.C., sent me a fossil vertebra, which was collected when he was associated with Dr. T. W. Stanton on an expeditionin Montana during the early autumnof 1914. This vertebra,when received by me, was labeled thus: "Coniornis altus Marsh, Lumbar vertebra, Dog Creek, I mi. above its mouth, Fergus County, Montana. CretaceousClagget formation(upper yellowish sandstone) September 26, 1914." T. W. Stanton, C. W. Gilmore. All. No." There being no proper material in the collectionsof the U.S. National Museum wherewith to comparethis vertebra, I studiedit as best I couldthrough comparing the fossilbone with the figures givenby Marsh in his Odontornithes.This comparisonconvinced me of the fact that the vertebra belongedto some medium-sized Hesperorn'is;further, that it more closelyresembled the 23d vertebra of the spinal colmnnof Hesperornisregalis than it did any other vertebra, and I was therefore led to believe that it was the correspondingvertebra of somespecies of Hcsperornis,smaller than H. regalis,probably of a speciesheretofore unclescribed. As I knew that Doctor Richard S. Lull, of the PeabodyMuseum, wasengaged upon a studyof the Hesperornithide*,at the time this bone came to me for study, I determinedto refer it to hi•n for an opinion. This 1 did with a letter datedat Washington,D.C., the 10th of November, 1914.
