British Polacanthid Dinosaurs - Addendum

Posted by David Penney on

As is often the case with published works, some errors do creep in that are not noticed until the book has been printed. The purpose of this blog post is to correct two small errors in our monograph on British Polacanthid Dinosaurs by William T. Blows. Click the cover image to go to the product page But first, a couple of weeks ago I took my daughter to the Natural History Museum in London where she was able to get hands on with spikes, plates and other fossilized elements of these remarkable dinosaurs. If you like dinosaurs then the Natural...

New Fossil Scorpion 290 Million-Years-Old Sheds Important Light on their Evolutionary History

Posted by David Penney on

Scorpion fossils are possibly more diverse than you might expect. 128 fossil species are currently recognized, with some dating back as far as the Silurian period. They occur in various different rock types and also, more rarely, as inclusions in amber. Fossil scorpion from the Cretaceous Crato Formation, Brazil A new discovery, representing the first complete scorpions from the Permian period, has just been announced at a conference held in Germany. The fossils originate from a recently excavated locality in Chemnitz, Germany. It appears that explosive volcanism preserved the remarkable specimens in situ as part of the palaeosol and bedrock...

New approaches to the evolution and identification of wasps

Posted by David Penney on

Wing venation patterns in insects provide useful characters with which to classify living and fossil insects. Recently, quantification of its shape using landmarks (morphometric analysis) has increased the potential of wing venation to distinguish individual taxa such as species. However, the use of wing landmarks in elucidating how the species are related to one another (phylogenetic analyses) remains largely unexplored. In research just published in the journal Cladistics, Adrien Perrard and colleagues tested landmark analysis under parsimony (LAUP) to include wing shape data in a phylogenetic analysis of hornets and yellow jacket wasps. Using 68 morphological characters, nine genes and wing...

A new genus of British dinosaur!

Posted by David Penney on

A new genus of British dinosaur has just been formally erected for Polacanthus rudgwickensis described by William T Blows in 1996. The specimen consists of one nearly complete dorsal vertebra, a dorsal vertebral centrum, an anterior caudal vertebra, fragments of other vertebrae, the proximal end of the left scapula with a fused coracoid fragment, a distal end of a humerus, a nearly complete right tibia, rib fragments, two dermal bones and many small fragments. Dorsal vertebra of the new genus in posterior, lateral and anterior views The new genus, Horshamosaurus Blows, 2015 is formally erected, justified and diagnosed, along with...
