We explore how 20 marine ecosystems in deep time (Late Jurassic)are characterised by AZTI’s Marine 21 Biotic Index (AMBI), and how the indices responded to natural perturbations. AMBI 22 is widely used to detect the impacts of human disturbance and to establish 23 management targets, and this study is the first application of these indices to a fossil 24 fauna. Our results show AMBI detected changes in past seafloor communities (well- 25 preserved fossil deposits) that underwent regional deoxygenation in a manner 26 analogous to those experiencing two decades of organic pollution. These findings 27 highlight the potential for palaeoecological data to contribute to reconstructions of 28 pre-human marine ecosystems, and hence provide information to policy makers and 29 regulators with greater temporal context on the nature of ‘pristine’ marine 30 ecosystems.

Why did the UV-A-induced photoluminescent blue–green glow in trilobite eyes and exoskeletons not cause problems for trilobites? PeerJ 3:e1492 https://doi.org/10.7717/peerj.1492 Why the UV-A-induced photoluminescent blue-green glow in trilobite eyes and exoskeletons did not cause problems for trilobites? Brigitte Schoenemann, Euan N.K. Clarkson, Gábor Hórváth The calcitic lenses in the eyes of Palaeozoic trilobites are unique in the animal kingdom, although the use of calcite would have conveyed great advantages for vision in aquatic systems. Calcite lenses are transparent, and due to their high refractive index they would facilitate the focusing of light. In some respects, however, calcite lenses bear evident disadvantages. Birefringence would cause double images at different depths, but this is not a problem for trilobites since the difference in the paths of the ordinary and extraordinary rays is less than the diameter of the receptor cells. Another point, not discussed hitherto, is that calcite fluoresces when illuminated with UV-A. Here we show experimentally that calcite lenses fluoresce, and we discuss why fluorescence does not diminish the optical quality of these lenses and the image formed by them. In the environments in which the trilobites lived, UV-A would not have been a relevant factor, and thus fluorescence would not have disturbed or confused their visual system.

Thus, we see vetulicolians assigned to groups as disparate as deuterostomes and ecdysozoans. This divergence of opinions revolves around a strikingly arthropod-like body, but one that also bears complex lateral structures on its anterior section interpreted as pharyngeal openings. Establishing the homology of these structures is central to resolving where vetulicolians sit in metazoan phylogeny. Results: New material from the Chengjiang Lagerstätte helps to resolve this issue. Here, we demonstrate that these controversial structures comprise grooves with a series of openings. The latter are oval in shape and associated with a complex anatomy consistent with control of their opening and closure. Remains of what we interpret to be a musculature, combined with the capacity for the grooves to contract, indicate vetulicolians possessed a pumping mechanism that could process considerable volumes of seawater. Our observations suggest that food captured in the anterior cavity was transported to dorsal and ventral gutters, which then channeled material to the intestine.

The tour is designed for those with an interest in studying the earth’s palaeontological record in unique environments across rural China. Palaeontologist Stephen Brusatte, in a 2018 interview with National Geographic, says “right now” is the golden age of discovery in dinosaur research, with experts finding about “50 new species a year”.

China, Brusatte says, “is the hot spot”. Cosmos magazine reports that 50 new feathered species of dinosaur have been discovered across China’s large landmass since 1996. More fossils, dinosaur footprints, and dinosaur tracks continue to turn up. You can read more in our article on Dinosaurs and Dinosaur Fossils.

  • Bundenbach (Hunsrück, BDR): Meestal Arm, Soms Rijk "Softe" Buikzijden Van Trilobieten Maken Vindplaats Wereldberoemd
    Bundenbach (Hunsrück, BDR): meestal arm, soms rijk "Softe" buikzijden van trilobieten maken vindplaats wereldberoemd door W.H. Südkamp *) In een Gea-special over trilobieten ver- dient de vindplaats Bundenbach (in de zuidelijke Hunsruck; deelstaat Rijnland- Palts; Duitsland) de nodige aandacht (foto 1). Hier werden tot voor kort - bij de produktie van dakleien - unieke en soms zelfs met de weke delen bewaard geble- ven fossielen gevonden. Dit heeft de Vroegdevonische vindplaats wereldbe• roemd gemaakt. Als we deze topstukken in een museum zien, moeten we ons beseffen dat Bundenbach op zich geen rijke vindplaats is, zoals vroeger bijvoor- beeld Vireux of Gerolstein. De leien zijn als regel fossielarm en het vinden van een volledig fossiel moet als uitzondering worden beschouwd. Daarbij komt, dat de kwaliteit meestal te wensen overlaat. Hiervoor zijn verschillende redenen: Ten eerste. De Bundenbach-fossielen zijn Foto 1. De Bundenbach-leisteen staat vrijwel verticaal in de "nieuwe" groeve Eschenbach-Bocksberg, die tussen gepyritiseerd maar de mate waarin dit gebeur- 1993 en 2000 in bedrijf was en waar de zg.

    FOUR Phylum CNIDARIA corals, medusae, hydroids, myxozoans STEPHEN D. CAIRNS, LISA-ANN GERSHWIN, FRED J. BROOK, PHILIP PUGH, ELLIOT W. Dawson, OscaR OcaÑA V., WILLEM VERvooRT, GARY WILLIAMS, JEANETTE E. Watson, DENNIS M. OPREsko, PETER SCHUCHERT, P. MICHAEL HINE, DENNIS P. GORDON, HAMISH J. CAMPBELL, ANTHONY J. WRIGHT, JUAN A. SÁNCHEZ, DAPHNE G. FAUTIN his ancient phylum of mostly marine organisms is best known for its contribution to geomorphological features, forming thousands of square Tkilometres of coral reefs in warm tropical waters. Their fossil remains contribute to some limestones. Cnidarians are also significant components of the plankton, where large medusae – popularly called jellyfish – and colonial forms like Portuguese man-of-war and stringy siphonophores prey on other organisms including small fish. Some of these species are justly feared by humans for their stings, which in some cases can be fatal. Certainly, most New Zealanders will have encountered cnidarians when rambling along beaches and fossicking in rock pools where sea anemones and diminutive bushy hydroids abound. In New Zealand’s fiords and in deeper water on seamounts, black corals and branching gorgonians can form veritable trees five metres high or more. In contrast, inland inhabitants of continental landmasses who have never, or rarely, seen an ocean or visited a seashore can hardly be impressed with the Cnidaria as a phylum – freshwater cnidarians are relatively few, restricted to tiny hydras, the branching hydroid Cordylophora, and rare medusae. Worldwide, there are about 10,000 described species, with perhaps half as many again undescribed. All cnidarians have nettle cells known as nematocysts (or cnidae – from the Greek, knide, a nettle), extraordinarily complex structures that are effectively invaginated coiled tubes within a cell.
