“…have been recorded from the Saltwick Formation, none of these ichnotaxa is particularly useful as a palaeosalinity indicator. Similar ichnofossil assemblages occur in the Silesian (mid-Carboniferous) rocks of the Central Pennine Basin (Eagar et al 1985), where a Pelecypodichnus ( Lockeia)-Kouphichnium-Arenicolites assemblage has been recognised from Lower Westphalian arenaceous non-marine strata. Despite the similarity of this assemblage to that from the Saltwick Formation at ichnogeneric level, it is premature to imply a similar ichnofacies until a more thorough taxonomic study is undertaken and the stratigraphic locations and associations of the ichnofaunas of the Yorkshire sequence are known in more detail.…”

The first record of xiphosurid (arthropod) trackways from the Saltwick Formation, Middle Jurassic of the Cleveland Basin, Yorkshire

ABSTRACT. Trackways attributed to a xiphosurid (arthropod) maker are described for the ®rst time from the Middle Jurassic Saltwick Formation, Ravenscar Group, of the Cleveland Basin, Yorkshire. The trackways are assigned to Kouphichnium aff. variabilis (Linck, 1949) and clearly demonstrate the heteropody and varied behaviour of the maker. Their occasional asymmetry indicates a slight rotation of the body relative to the direction of locomotion. The Saltwick Formation has generally been regarded as a coastal plain deposit, and the presence of xiphosurid tracks reinforces the suggestions of periodic marine in¯uences.

“…Palaeocurrent measurements taken from sedimentary structures indicate low divergence around a mean palaeoflow towards the east-southeast ( Figure 5). Observed biogenic structures include rare ?PaZaeophycus and Arenicolites burrows at bed tops, and a single specimen of Kouphichniurn (a xiphosurid trail; see Eager et al 1985). Flattened impressions of plant stemdtrunks are preserved as coaly traces on some bedding planes.…”

Lower delta plain interdistributary deposits — An example from the Westphalian of the Lancashire Coalfield, northwest England

A large quarry at Billinge Beacon in Lancashire, northwest England, has provided an excellent exposure of part of the Lower Westphalian A (Upper Carboniferous) Coal Measures sequence which was deposited in a lower delta plain setting. The main horizon exposed, known as the Dyneley Knoll Flags, is interpreted as the proximal reaches of two crevasse-initiated minor delta complexes, into the lower of which has been incised a sinuous minor distributary channel.The channel, which was approximately 120 m wide, built a 160 m wide channel belt by limited lateral accretion with time; vertical accretion appears to have been the dominant infilling mechanism. This produced a stacked series of epsilon cross-strata, made up of rhythmically interbedded sandstone and silty claystone. The peculiar style of infilling of the channel is ascribed to deep incision of the channel into minor delta deposits, and possibly the influence of a seasonal climate.

“…Grazing, feeding, locomotion, and predation are the main ethologic behaviors represented by Cochlichnus (Eagar et al, 1985;Dam, 1990;Netto, 1992;Buatois & Mángano, 1993;Głuszek, 1995;Buatois et al, 1997;Sarkar et al, 2009), being recorded in marine, marginal-marine and continental subaquatic environments, including lacustrine (e.g. Buatois & Mángano, 1993, 1995Gibert et al, 2000;Netto et al, 2009;Uchman et al, 2009), deltaic (Eagar et al, 1985;Melchor et al, 2003) and fluvial deposits (see compilation by (Keighley & Pickerill, 1996). The presence of discrete scratch marks and of uniformly shallow, narrow lobes is diagnostic of C. problematica (e.g.…”

-The ichnofauna of the Teresina Formation from the Cerro Caveiras (Dom Pedrito, Rio Grande do Sul State, South Brazil) is revised in this paper. Bergaueria isp., Cochlichnus cf. anguineus, Cruziana problematica, cf. Diplocraterion isp., Diplopodichnus biformis, Helminthopsis isp., Lockeia siliquaria, Multina arcuata isp. nov., Oldhamia isp., Palaeophycus striatus, P. tubularis, Phymatoderma burkei, Planolites beverleyensis, P. montanus, Teichichnus isp., and Thalassinoides isp. were recorded. Isopodichnus problematicus, Helminthopsis tenuis and Unarites isp., previously described in these deposits are now described as Cruziana problematica, indeterminate molluscan trail, and Multina arcuata isp. nov., respectively. The ichnofauna is composed chiefly of horizontal, simple shallow burrows, with a predominance of feeding structures. Resting, dwelling and crawling structures also occur, as well as indeterminate tiny grazing trails, but are less frequent. Ichnodiversity and intensity of bioturbation are usually low, and P. montanus is the commonest ichnotaxon. The main characteristics of the ichnofauna suggest a marine benthic fauna stressed by salinity fluctuations and resulting in an impoverished Cruziana ichnofacies. The absence of vertical burrows and the common occurrences of monospecific assemblages of Planolites indicate extreme stress events, probably due to the establishment of freshwater conditions. Further studies focused on the ichnological signatures of these deposits will provide more detailed information to improve the current paleoecologic and paleoenvironmental interpretations of the Teresina Formation deposits.
