Faunal turnover of marine tetrapods during the Jurassic–Cretaceous transition
- R. Benson, P. Druckenmiller

- Biological reviews of the Cambridge Philosophical…
- 1 February 2014
Marine and terrestrial animals show a mosaic of lineage extinctions and diversifications during the Jurassic–Cretaceous transition. However, despite its potential importance in shaping animal… Expand
High Diversity, Low Disparity and Small Body Size in Plesiosaurs (Reptilia, Sauropterygia) from the Triassic–Jurassic Boundary
- R. Benson, Mark Evans, P. Druckenmiller
- Biology, Medicine
- PloS one
- 16 March 2012
Invasion of the open ocean by tetrapods represents a major evolutionary transition that occurred independently in cetaceans, mosasauroids, chelonioids (sea turtles), ichthyosaurs and plesiosaurs.… Expand
A phylogeny of Plesiosauria (Sauropterygia) and its bearing on the systematic status of Leptocleidus Andrews, 1922
- P. Druckenmiller, A. P. Russell
- Biology
- 3 September 2008
Leptocleidus Andrews, 1922 is a poorly known plesiosaur genus from Lower Cretaceous successions of the UK, South Africa, and Australia. Historically, there has been little consensus regarding its… Expand
A new Lower Cretaceous (lower Albian) ichthyosaur genus from the Clearwater Formation, Alberta, Canada
- P. Druckenmiller, E. Maxwell
- Geology
- 20 August 2010
A new, articulated skeleton of an ichthyosaur from the Lower Cretaceous (lower Albian) Wabiskaw Member of the Clearwater Formation near Fort McMurray, Alberta, is the most complete and… Expand
A New Upper Jurassic Ophthalmosaurid Ichthyosaur from the Slottsmøya Member, Agardhfjellet Formation of Central Spitsbergen
- A. Roberts, P. Druckenmiller, Glenn-Peter Sætre, J. Hurum
- Biology, Medicine
- PloS one
- 1 August 2014
Abundant new ichthyosaur material has recently been documented in the Slottsmøya Member of the Agardhfjellet Formation from the Svalbard archipelago of Norway. Here we describe a partial skeleton of… Expand
Two new species of long-necked plesiosaurians (Reptilia: Sauropterygia) from the Upper Jurassic (Middle Volgian) Agardhfjellet Formation of central Spitsbergen
- Espen M. Knutsen, P. Druckenmiller, J. Hurum
- Biology
- 2012
At present, very little is known regarding the diversity and morphological disparity of long-necked plesiosaurs in Tithonian-aged (latest Jurassic) units globally. Here, we describe two species of a… Expand

Two new ophthalmosaurids (Reptilia: Ichthyosauria) from the Agardhfjellet Formation (Upper Jurassic: Volgian/Tithonian), Svalbard, Norway
- P. Druckenmiller, J. Hurum, Espen M. Knutsen
- Biology
- 2012
Ichthyosaur diversity near the Jurassic-Cretaceous boundary, particularly from high paleolatitudes, is poorly known. Two recently collected specimens of medium- to large-bodied ichthyosaurs from the… Expand

Plasticity and Convergence in the Evolution of Short-Necked Plesiosaurs
- V. Fischer, R. Benson, +6 authors P. Druckenmiller
- Biology, Medicine
- Current Biology
- 5 June 2017
Plesiosaurs were the longest-surviving group of secondarily marine tetrapods, comparable in diversity to today's cetaceans. During their long evolutionary history, which spanned the Jurassic and the… Expand
Hydrocarbon seeps from close to the Jurassic-Cretaceous boundary, Svalbard
- Øyvind Hammer, H. A. Nakrem, +6 authors Magne Høyberget
- Geology
- 1 June 2011
Fifteen carbonate bodies, interpreted as having been formed at hydrocarbon seeps, have been found in the Sassenfjorden area of Spitsbergen, Svalbard. The bodies, up to 5 m wide, are found in the… Expand
A new Plesiosauroid (Reptilia: Sauropterygia) from the Agardhfjellet Formation (Middle Volgian) of central Spitsbergen, Norway
- Espen M. Knutsen, P. Druckenmiller, J. Hurum
- Geology
- 2012
At present, our knowledge of plesiosauroid diversity from the uppermost Jurassic (Tithonian/Volgian) is very limited. Newly discovered material from the Slottsmoya Member of the Agardhfjellet… Expand
