research

As an artist and illustrator I see myself as a mediator between research and publicity. Staying linked to science due to my studies and research contains the following aspects...

On a special extended stand, the drill was used to sample another pelycosaur. A well earned BBQ after a challenging but successful day! Courtesy of Johannes Richter (geol. survey), Martin Sander, Jörg Schneider, Christen Shelton, Nico Richter, and Marcel Hübner.

 

 

2013 meetings

I contributed to the annual meetings of Paläontolgische Gesellschaft (joint meeting with the Chinese Paleontological Society, Göttingen) and Society of Vertebrate Paleontology (L.A.) - a lot of fun, meeting friends and lerning much about ancient life… and sketching of course

The sphenacodont poster was elected the 1st poster prize. Many thanks to my co-authors Graciela Pineiro and Kirstin Brink!

research in summer 2012

I've done several documentation journeys to European collections that house pelycosaur remains: Warwick (England), Paris, Berlin, Thallichtenberg. Our excavation in Oberhof (Thuringia) was about the environmental history of an Early Permian lake ecosystem.

documentation of early amniote fossils

Documentary sketches before the final drawing help to clear up the anatomy and preservation. Tracing paper over colored print-out, scaled to 200% of natural size, by observing the fossils and casts.

casts of early amniote fossils

For my planned dissertation some Permian amniote fossils have to be cast. The soft bones have left natural casts in the limestone that can be documented as the original shapes when molded with silicone.

casts of a stagonolepid armor plate

Before sampling thin sections, these armor plates of a stagonolepid archosaur have been cast to preserve their shape data. (Carried out for Michael Buchwitz)

dinosaurs

For some years I have pursued dinosaur publications. Due to increasing activities I lost the view over all new species. Also drawing dinosaurs had to be decreased. Here I show you some of the older drawings: some skeletons  (Piatnitzkysaurus, Procompsognathus und Shuvuuia) from the so-called special study effort for my secondary school qualification (2002), raptor table, sauropod skulls, and the cranial reconstruction of Buitreraptor. As you see, theropods are focused. More dinosaurs within this gallery.

pelycosaurs

Through my diploma thesis I came to pelycosaurs (ancestors of mammal-like reptiles). It was then about Pantelosaurus, the documentation of their skeletal aggregation, anatomy and biology. We're going to study all haptodonts, including revision and biological interpretation. Here are some old drawings from my thesis. Also the posters seen above belong to that effort. More pelycosaurs can be seen in the galleries among any reconstructions and scientific style.

Spindler, F. (2008): Klassifikation, Taphonomie und Palökologie des „Haptodus“-Komplexfundes aus dem Perm des Döhlen-Beckens. – unpublished diploma thesis, Freiberg.

geology: clastic dykes

For the qualification I passed my field mapping in 2009, dealing with clastic dykes from the Döhlen basin, Freital (Saxony). These are earthquake fissures, of which I had to document their structures and distribution. Only few fossils, mainly algae and terrestrial plant roots could be collected. Hope to publish the data one day...

geology: Permian profile

Among the field mappings during the academic studies, there was a profile documentation in the French Permian rocks of the Lodéve basin. It's a playa facies with channel systems.

geology: excavations

Determined by the Freiberg research team, excavations also have been carried out in the Permian rocks. I joined fossil collection activities in Thuringia, Saxony, the Czech Republic and France.
