Leonardo da Vinci and palaeontology | part 2 (Click this link for part 1) What is the true nature of petrified shells? Background picture from Leonardo's Codex. Among the corpus of Leonardo’s writings, the Codex Leicester has been acknowledged as a fundamental document in the…
Read MoreThe Jurassic Beach is an exceptional fossil site in Portugal. Special techniques are needed to study its exceptional fossil content. Above, Jose Antonio Anacleto and Ricardo Paredes are casting trace fossils at the Jurassic Beach palaeontological site (Praia Jurássica). Me waring protectionsKneeling on Jurassic limestones…
Read MoreJurassic Beach? Yes, there is a beach dating back to the age of dinosaurs (Praia Jurássica) near Porto de Mós, Portugal. I recently joined the Jurassic Beach team to study this exceptional palaeontological site! Here is the Jurassic Beach team! From the foreground to the…

Ichnosummer 2019 has been a success! In fact, during fieldwork in Portugal, I discovered thousands of beautiful trace fossils. Now it is time to go from aesthetics to science, i.e. I need to understand the behaviours of those spectacular burrows. The beauty of these trace…
Read MoreIchnosummer 2019 started in Portugal! This will be a period of intense fieldwork in the Palezoioic and Mesozoic units of Iberia. Here I am (left) with Carlos Neto de Carvalho (right). What will we find in the Ordovician rocks of UNESCO Geopark Naturtejo?

The seafloor of the Ligurian Sea is more than an expanse of sand. In fact, it often features traces of life-substrate interactions, such as these circular 'craters'. What are they? They are feeding pits produced by fishes, almost identical to the trace fossil Piscichnus. This…

This photo gallery documents my typical day on the field during autumn times. I check field tools on the beach, I start up my GPS-equipped camera, then I fit into the wetsuit... and then I splash into the cold water! Succesively, my fieldwork basically consists…

Just as its name implies, a quadrat is a square frame. Despite its simplicity, the imaged quadrat plays a fundamental role in my research about modern traces of life-substrate interactions. In fact, I place the quadrat on the seafloor and then the traces within that…

Below the seafloor surface lies a vast, complex ecosystem, one of the Earth’s lesser-known environments. Here, marine animals produce complex burrow systems: What is the function of these structures? What is their distrubution? How did they evolve during the last 600 million years? I am…

Today I continued conducting quadrat sampling in the amazing Ligurian Sea. This series of photos shows a quadrat sampling session - from snorkelling to spotting a burrow with a mound! Each and every quadrat-based observation is georeferenced by GPS, so that in the laboratory I…

Today I photographed paired openings on the seafloor. These openings have been produced by burrowing bivalves (clams) to keep contact with the oxygenated seawater. The fossil burrows Siphonichnus and Teichichnus are possible analogues of this burrow system, spotted on the sandy seafloor of the Ligurian…

On some seafloors of the Ligurian Sea, sediment mounds tower smaller openings. Each mound is likely to be connected with the nearby openings, forming a tunnel system that resembles the fossil burrow Thalassinoides. Thalassinoides is a genus of fossil burrow consisting of horizontal branched tunnels…
