IV.—On some new Crustaceans from the Lower Carboniferous Rocks of Eskdale and Liddesdale

Abstract

By the permission of Professor A. C. Ramsay, LL.D., F.R.S., Director-General of the Geological Survey of Great Britain and Ireland, and Professor Geikie, LL.D., F.R.S., Director of the Geological Survey of Scotland, I have been permitted to describe several new Crustaceans which have come under my notice in my capacity of Acting Palæontologist to the Scotch Survey. They are from the cement-stone group of the Calciferous Sandstone series of the Scottish border, and, with a very few exceptions, were got from one locality on the river Esk, about four miles south of Langholm, in Dumfriesshire, and were almost all collected by A. Macconochie, Fossil Collector to the Geological Survey of Scotland. They belong to two orders, viz., Phyllopoda and Decapoda.

Gas-phase mean opacities for varying [M/H], N/O and C/O

“…We include continuum opacity sources (H i : Karzas & Latter 1961; H−: John 1988; H+H: Doyle 1968; H − 2 : Somerville 1964; H + 2 : Mihalas 1965; He i : Peach 1970; He−: Carbon, Gingerich & Latham 1969; and C i , Mg i , Al i and Si i : Peach 1970; Thomson scattering and Rayleigh scattering for H i and He i : Dalgarno 1962). The line opacity sources are taken from the Copenhagen SCAN data base (CO: Goorvitch & Chackerian 1994; TiO: Jørgensen 1994b; SiO: Langhoff & Bauschlicher 1993; H 2 O: Jørgensen & Jensen 1993; CH: Jørgensen et al 1996; CN: Jørgensen & Larsson 1990; C 2 : Querci, Querci & Tsuji 1974; C 3 : Jørgensen, Almlof & Siegbahn 1989; HCN and C 2 H 2 : Jørgensen 1990, in an updated version; H 2 –H 2 and H 2 –He collision induced absorption (CIA) from Borysow 2002 and private communication), and were extended (Schnabel 2001) by the HITRAN data base (CH 4 , NH 3 , CO 2 , SO 2 , NO 2 , NO, OH, N 2 : Rothman et al 2003).…”

First decapod crustaceans in aLateDevonian continental ecosystem

“…Clark (), in a revision of the Tealliocaris Peach, material from the Carboniferous of Scotland, highlighted a suite of characters indicating a closer relationship to decapod crustaceans, in particular Astacida, Homarida and Glypheoidea, than to any other crustacean clade. Tealliocaris had previously been recorded from the Carboniferous of Scotland (Etheridge ; Peach , , ; Briggs and Clarkson ; Cater et al . ; Briggs et al .…”

Redescription of Opsipedon Gracilis Heer (Crustacea, Tanaidacea) from the Middle Jurassic of Northern Switzerland, and the Palaeoenvironmental Significance of Tanaidaceans

“…The three described species of these ages are Anthracocaris scotica (Peach, 1882) from the Lower Carboniferous of Scotland (Schram et al 1986;Briggs et al 1991), Eucryptocaris asherorum Schram, 1989(pro Cryptocaris hootchi Schram, 1974) from the Upper Carboniferous of Mazon Creek, Illinois (Schram et al 1986;Schram 1989) and Ophthalmapseudes rhenanus (Malzahn, 1957) from the Lower Permian of northern Germany (Schram et al 1986). All of these species possess six free pleomeres and a small telson which is the diagnostic feature of the suborder Anthracocaridomorpha Sieg, 1980.…”
