Kenworthy George Washington Memorial Parkway Turkey Run Park McLean, VA 22101 Geologic Resources Division Technical Report NPS/NRGRD/GRDTR-05/01 September 2005 DEDICATION Fran Barnes and his wife Terby, residents of Moab who lived in the area for over 30 years, were in the unique position of having a more comprehensive understanding of the region’s potential paleonto- logic resources than many, if not all, scientists who venture here for research purposes. Fran and Terby explored the canyon country extensively and were extremely knowledgeable of historical, prehistorical, and paleontological resources within the region as well as trail systems. Fran’s unflagging efforts to alert scientists to his discoveries as well as his own initiative in reporting localities and his interpretations thereof through his own publications were exceptional. His vitality and enthusiasm still lured him into the field twice weekly, despite being over 80 years old (in 2002). In recognition of his contributions to the scientific intrigue of canyon country, we dedicate this volume to Fran Barnes, who passed away in 2003. He will be sorely missed.

Here we report on the composition of the Cliffs of Insanity (COI) microvertebrate locality, a newly sampled site containing perhaps one of the densest concentrations of microvertebrate fossils yet discovered in the Mussentuchit Member. The COI locality preserves osteichthyan, lissamphibian, testudinatan, mesoeucrocodylian, dinosaurian, metatherian, and trace fossil remains and is among the most taxonomically rich microvertebrate localities in the Mussentuchit Submitted 30 May 2018 fi fi Accepted 8 October 2018 Member.

    AmelanchierAmelanchier canadensiscanadensis ShadblowShadblow serviceberry,serviceberry, CanadianCanadian serviceberry,serviceberry, DownyDowny serviceberry,serviceberry, Shadbush,Shadbush, Juneberry,Juneberry, ChuckleberryChuckleberry Amelanchier canadensis(Shadblow serviceberry) is native to South Canada and the eastern United States. The shrub was introduced in Europe in 1746. The Shadblow serviceberry grows up to 5 to 6 metres tall and wide with a finely branched, wide vase-shaped crown. Before the leaves start to sprout, the Amelanchier canadensisblooms bountifully racemes of white flowers that hang over slightly. In late July, it bears red-violet to blue-black fruits that are edible. The leaves are relatively large and bud in a lovely bronze-red. In the summer, the Shadblow serviceberry has green leaves with a grey-green underside. The autumn colours are yellow-orange to brown and less striking than those of other serviceberry shrubs. The species has a preference for sunlight and moist, humous, slightly acidic soil. It will tolerate a temporarily dry environment, as well as strong wind. That makes Amelanchier canadensis very suitable for use in containers and roof gardens.

  • Chromosome Numbers in Compositae, XII: Heliantheae
    SMITHSONIAN CONTRIBUTIONS TO BOTANY 0 NCTMBER 52 Chromosome Numbers in Compositae, XII: Heliantheae Harold Robinson, A. Michael Powell, Robert M. King, andJames F. Weedin SMITHSONIAN INSTITUTION PRESS City of Washington 1981 ABSTRACT Robinson, Harold, A. Michael Powell, Robert M. King, and James F. Weedin. Chromosome Numbers in Compositae, XII: Heliantheae. Smithsonian Contri- butions to Botany, number 52, 28 pages, 3 tables, 1981.-Chromosome reports are provided for 145 populations, including first reports for 33 species and three genera, Garcilassa, Riencourtia, and Helianthopsis. Chromosome numbers are arranged according to Robinson’s recently broadened concept of the Heliantheae, with citations for 212 of the ca. 265 genera and 32 of the 35 subtribes. Diverse elements, including the Ambrosieae, typical Heliantheae, most Helenieae, the Tegeteae, and genera such as Arnica from the Senecioneae, are seen to share a specialized cytological history involving polyploid ancestry. The authors disagree with one another regarding the point at which such polyploidy occurred and on whether subtribes lacking higher numbers, such as the Galinsoginae, share the polyploid ancestry. Numerous examples of aneuploid decrease, secondary polyploidy, and some secondary aneuploid decreases are cited. The Marshalliinae are considered remote from other subtribes and close to the Inuleae. Evidence from related tribes favors an ultimate base of X = 10 for the Heliantheae and at least the subfamily As teroideae. OFFICIALPUBLICATION DATE is handstamped in a limited number of initial copies and is recorded in the Institution’s annual report, Smithsonian Year.
