Scythes, sickles and other blades: defining the diversity of pectoral fin morphotypes in Pachycormiformes
The traditional terminology of ‘scythe’ or ‘sickle’ shaped is observed to be flawed as an effective descriptor for pectoral fin shape in pachycormids. The diversity of pachycormid pectoral fin shapes is assessed across the 14 recognised genera that preserve complete pectoral fins, and improved terms are defined to more effectively...Liston, Jeff

Cranial osteology of the Middle Jurassic (Callovian) Martillichthys renwickae (Neopterygii, Pachycormiformes) with comments on the evolution and ecology of edentulous pachycormiforms
Our understanding of the ecology and phylogenetic relationships of Pachycormiformes, a group of Mesozoic stem teleosts including the iconic Leedsichthys, has often been hindered by a lack of comprehensive morphological information. Micro‐CT scanning of an articulated, although flattened, cranium of the edentulous Martillichthys renwickae from the Middle Jurassic (Callovian) Oxford...Dobson, Claire ; Giles, Sam ; Johanson, Zerina ; Liston, Jeff ; Friedman, Matt

Additional sauropod dinosaur material from the Callovian Oxford Clay Formation, Peterborough, UK: evidence for higher sauropod diversity
Four isolated sauropod axial elements from the Oxford Clay Formation (Callovian, Middle Jurassic) of Peterborough, UK, are described. Two associated posterior dorsal vertebrae show a dorsoventrally elongated centrum and short neural arch, and nutrient or pneumatic foramina, most likely belonging to a non-neosauropod eusauropod, but showing ambiguous non-neosauropod eusauropod and...Holwerda, Femke M ; Evans, Mark ; Liston, Jeff

Assessing metabolic constraints on the maximum body size of actinopterygians: locomotion energetics of Leedsichthys problematicus (Actinopterygii, Pachycormiformes)
Maximum sizes attained by living actinopterygians are much smaller than those reached by chondrichthyans. Several factors, including the high metabolic requirements of bony fishes, have been proposed as possible body‐size constraints but no empirical approaches exist. Remarkably, fossil evidence has rarely been considered despite some extinct actinopterygians reaching sizes comparable... -

Ivory Towers of entitlement?: the commercialisation of academic palaeontologists
Palaeontology suffers from divisions amongst its community, along an ostensibly motivational division between acadmic and commercial palaeontologists, the former not being motivated financially, unlike the latter. These divisions are particularly plarised in the United States of America. In order to discuss why this attitude exsists, even when the financial division...Liston, Jeff

Ivory piano keys from Mastodons: Why poor anthropocentic legislation endangers fossils
Palaeontological material and sites have faced a variety of challenges in the last half century, often due to inadequate legislation from poorly informed legislators designed for very different objects. The most common problematic scenario is for material to be assessed on anthropocentic grounds that are more traditionally applied to archaeological...Liston, Jeff

New ophthalmosaurid ichthyosaurs from the European Lower Cretaceous demonstrate extensive ichthyosaur survival across the Jurassic-Cretaceous boundary.
Background Ichthyosauria is a diverse clade of marine amniotes that spanned most of the Mesozoic. Until recently, most authors interpreted the fossil record as showing that three major extinction events affected this group during its history: one during the latest Triassic, one at the Jurassic–Cretaceous boundary (JCB), and one (resulting...Fischer, Valentin ; Maisch, Michael W ; Naish, Darren ; Kosma, Ralf ; Liston, Jeff …

A basal thunnosaurian from Iraq reveals disparate phylogenetic origins for Cretaceous ichthyosaurs
Cretaceous ichthyosaurs have typically been considered a small, homogeneous assemblage sharing a common Late Jurassic ancestor. Their low diversity and disparity have been interpreted as indicative of a decline leading to their Cenomanian extinction. We describe the first post-Triassic ichthyosaur from the Middle East, Malawania anachronus gen. et sp. nov....Fischer, Valentin ; Appleby, Robert M ; Naish, Darren ; Liston, Jeff ; Riding, James B …

Alfred Nicholson Leeds and the first fossil egg attributed to a ‘saurian’
Discovered by the nineteenth century collector Alfred Nicholson Leeds, the first object to be described (1898) as a fossil reptile egg is a unique find from the Oxford Clay near Peterborough. It also comes from one of a very small number of Jurassic localities worldwide that can claim to have...Liston, Jeff
