Field trip to the Antwerp Harbour area, Belgium

Harry Meisner (Germany) The Antwerp harbour area in Belgium is a very interesting spot for finding fossils. In October 2010, the port approved a long-term investment plan, worth €1.6 billion over the next 15 years. As a result, for a while, the whole area became one big fossiliferous outcrop as a result of the construction of new docks (this is no longer the case). Fig. 1. The Antwerp harbour area in Belgium is a very interesting spot for finding fossils. Here, you could find sediments from the Miocene and Pliocene (the Kattendijk Sands, which form the base of the Pliocene in Belgium). These deposits originally occurred on top of the Oligocene Boom Clay, but are now disturbed and have been brought to the surface by the construction works. The sand from the harbour basins was pumped by suction excavators through huge pipelines, to be deposited in large, man-made sand dunes. A few of these lie near the A12 Highway in the small city Stabroek. Normally, access to these dunes was strictly forbidden because of their dangerous nature, for example, the existence of quicksands and the possibility of being buried under sand. However, in the summer holidays, work stopped for a few weeks and, during that time, you could dig for fossils. During the summer 2008, I got a hint from one of my Dutch friends and so went to Stabroek with my son and friends, Oliver Sichelschmidt and Martin Wundram (the latter took the photos accompanying this article). When we … Read More

Book review: Cro-Magnon: The Story of the Last Ice Age People of Europe, by Trenton W Holliday

The Cro-Magnons were a population of early modern humans (that is, they were physically indistinguishable from us, today), who lived in Europe between about 40,000 and 10,000 years ago, during the Upper Palaeolithic period. This information comes from Trenton Holliday’s excellent book, which tells the story of these people in the context of recent scientific advances. However, while it does not shy away from complex scientific issues, the book is written with a light, understandable touch.

Chirotherium sp.

Rob Hope (France) For many years, a great number of Permian fossil footprints have been found in the red mudstone horizons of France’s Lodéve basin (Fig. 1). I have spent some time researching the fossils of this barren region, including learning from papers written by an array of specialists, as well as visiting museum and university collections of fossils from the area. My self-appointed investigation eventually took me to an obscure and overgrown uranium quarry in the heart of the Lodévian badlands. There, I discovered in situ footprint fossils, and rocks showing ripple marks as well as the traces of ancient Permian raindrops. Fig. 1. Simplified illustration showing the geology around the area known as the Lodéve Basin, in southernFrance (Hope, 2008). Later, while researching the Lodéve region further still, I came across yet more palaeontological papers concerning a later geological time – that of the Anisian stage of the Middle Triassic (240 million years ago). And, once again, the dark mudstone fossils from this particular sequence include enigmatic fossil footprints. There are for example traces of Rotodactylus sp., which some authors have described as the trails of a primitive dinosaurian. In addition, the distinctive trace fossil, Chirotherium sp. has also been found. Fossil prints from this Triassic ichnospecies (that is, categories of morphologically distinctive trace fossils)have been excavated throughout the world and were first described in 1835, by J Kaup. During the hundred years following their initial discovery, they caused heated debate within academic society, because the pes and … Read More

Stones that illustrate themselves

Deborah Painter (USA) Earlier in the month of September 2022, my friend David and I spent an afternoon with a fellow named Ellery, a long-time member of a rock collecting club we joined a year ago. Ellery allowed me to photograph some of his rock and mineral specimens, including a rough piece of ‘wonderstone’ of approximately 30cm in length and 19cm in width, from southern Utah, USA (Fig. 1). Fig. 1. Shinarump Wonderstone is a variety of chalcedony that features swirls and other decorative patterns. (Credits: Deborah Painter; specimen from the collection of Ellery Borow.) The piece contained what looked like a painting of the flanks of a slot canyon one might see in the very area where it is found (Fig. 2). Fig. 2. A slot canyon in Page, Arizona USA, just 180km to 185km from known sources of Shinarump Wonderstone. It reminds one of the ripples and swirls in the Wonderstone in Fig. 1. (Credits: Brigitte Werner, Pixabay.) On the opposite side of the same specimen was a fish’s head, complete with an ‘eye’ (Fig. 3). Fig. 3. This ‘fish head’, complete with a fishy ‘eye’ is the image that greets you when you turn over the Shinarump Wonderstone specimen in Fig. 1. (Credits: Deborah Painter; specimen from the collection of Ellery Borow.) None of the images were artificial or cut in a particular way to bring out these ‘images’. I was instantly reminded of the pietra paesina stones of the Florence area of Italy. The latter have … Read More

It doesn’t always have to be dinosaurs – a short review of rauisuchian archosaurs

Stephan Lautenschlager (Germany) and Dr Julia Brenda Desojo (Argentina) Fig. 1. Reconstruction of Batrachotomus kupferzellensis. (Museum of Natural History, Stuttgart, Germany.) Among the multitude of fossil animals, dinosaurs have always been the most popular and fascinating. Loved by six-year-olds, Hollywood directors, toy-designers and scientists alike, they not only dominated most of the Mesozoic Era, but still dominate our understanding of palaeontology. However, only a few people are aware that, before the dinosaurs started their 150-million-year-long global dominion, there was an equally successful and remarkable group of fossil reptiles – the ‘rauisuchians’ (Fig. 2). In this article, we will try to shed some light on these enigmatic and commonly unknown tetrapods, which were as adapt and predominant in their time – and, to be honest, as cool – as the dinosaurs. Fig. 2. Occurrence and evolution of the major archosaur groups. A history of rauisuchian research The first rauisuchian fossil was found in 1861 by the German naturalist Hermann von Meyer. It consisted of a single maxilla of Teratosaurus suevicus and was identified as an early dinosaur. The same happened to the next to be found, Poposaurus gracilis, after its discovery in Wyoming in 1915. This specimen was subsequently described as a theropod dinosaur, a primitive stegosaurid and also an ornithopod. Only when the German palaeontologist, Friedrich von Huene, collected numerous Triassic fossils from the Santa Maria Formation of Brazil in 1928, did things begin to change. His detailed studies of the material revealed that most of it did not belong … Read More

Fossil from Denmark (part 2)

Niels Laurids Viby (Denmark) The first half of the Palaeocene in Northern Europe belongs, more or less, to the Danish! On 16 November 1846, Edouard Desor held a lecture in Paris with the title ‘Sur l’étage Danien, nouvel étage de la crai’ (‘On the Danien, a new stage of the Cretaceous’) – the Danien was, at that time, seen as being the final stage of the Cretaceous period. Nowadays, in most parts of the world, including most of Europe, ‘Danien’ is the recognised name for the geological age stretching from the end of the Cretaceous (somewhere between 64 and 65mya, depending on what book you read) to some five million years later. Danien deposits are widespread in Denmark, apart from in the southern part of Jutland, and even here you can find flint and blocks of chalk from hardened Danien beds on every stony beach. For fossil collectors from countries that do not have these sediments, Denmark is a good place to visit – it is virtually impossible to come home without at least some Danien fossils, although probably not a great variety unless you visit Fakse Chalk Quarry (which is discussed below). Danien chalk – a lot of different sediments: Stevns Klint The layout of the Danien is best seen at Stevns Klint on Zealand, which has some 20km of cliffs, averaging 20m in height. Fig. 1. Stevns Klint – southern end. Here, the bottoms of the cliffs are, in most places, Cretaceous, being from the very top of … Read More

Building stones of the Ancient World

By Ken Brooks (UK) Local stone was an essential element in the development of early civilisations, as its availability and quality determined the building styles that they created. The effective working and use of stone as a building material was a skill acquired by man at an early stage of history in many different regions of the world. Today, we can identify their methods of working stone by studying the buildings, quarries and the tools that have survived them. Egypt For thousands of years, the River Nile has carved its way through areas of sandstone, granite and limestone on its 750-mile journey through Egypt to the Mediterranean. From very early times, and even to the present day, the Egyptians have built their homes with bricks made from mud – an abundant raw material along the banks of the River Nile. It was around 5,000 years ago, as organised religion became established, that they began to use locally available stone to construct temples and pyramids. Between 2590BC and 2500BC, the ancient Egyptians built three huge pyramids on the Giza plateau (near present-day Cairo). Fig. 1. The pyramids at Giza. The bedrock in this area is a nummulitic limestone dating from the Eocene period, 34 to 55mya. It is an interesting thought that some of the largest man-made structures on earth were constructed from the fossil remains of tiny organisms (foraminifera). Work on a pyramid began with the extraction of limestone blocks at a nearby quarry. The only tools the Egyptians had … Read More

Fossils from Denmark (part 1)

By Niels Laurids Viby Denmark – why on earth should anybody in the UK go to such a strange place – where people, among other things, drive on the wrong side of the road and speak a funny language? And why write something for Deposits on the subject at all? You can find fossils from almost every time period apart from a few in the UK. For example, you can find them from the very top of the Cretaceous period (Maastricien) and the Lower Palaeocene period (Danien). However, these particular geological periods, especially the Danien that was, after all, named after a site in Denmark are also found in many places in Denmark. Moreover, at one site, you can actually access the KT border and get a sample from the famous (but thin) band with high concentrations of iridium. Of course, most fossil collectors concentrate on what is found close to home, and for good logistical reasons. However, for those who want a broad collection covering the development of life or for that matter a mass extinction, a holiday in Denmark is a good option for filling a gap without having to drive long distances – Denmark is a rather small country! In this first article on Danish geology, I will provide the reader with two things. Firstly, a short description of Danish geology, including what is legal to collect and what is not and secondly, a description of a Danish speciality – Lower Eocene diatom clay, the ‘moler’, which … Read More

Book review: Iceland: Classic Geology in Europe (3rd edition), by Thor Thordarson and Ármann Höskuldsson

reviewed the 2nd edition of this guide a while ago and, as I said then, Iceland seems to set the hearts of certain geologists racing and, reading this field guide and that previous incarnation, it is abundantly clear why. Iceland’s fascinating geology is clearly set out in this concise and authoritative book. The island, astride the Mid-Atlantic Ridge, is a ‘natural laboratory’ where the earth sciences can be watched in real-time. Rifting of the crust, volcanic eruptions and glacial activity are among a host of processes and features that can be observed in this fascinating land.
