New spinosaurids from the Wessex Formation (Early Cretaceous, UK) and
the European origins of Spinosauridae
Abstract
Spinosaurids are among the most distinctive and yet poorly-known of large-bodied theropod dinosaurs, a situation exacerbated by their
mostly fragmentary fossil record and competing views regarding their palaeobiology. Here, we report two new Early Cretaceous spinosaurid
specimens from the Wessex Formation (Barremian) of the Isle of Wight. Large-scale phylogenetic analyses using parsimony and Bayesian
techniques recover the pair in a new clade within Baryonychinae that
also includes the hypodigm of the African spinosaurid Suchomimus. Both specimens represent distinct and novel taxa, herein named
Ceratosuchops inferodios gen. et sp. nov. and Riparovenator milnerae
gen. et sp. nov. A palaeogeographic reconstruction suggests a European
origin for Spinosauridae, with at least two dispersal events into
Africa. These new finds provide welcome information on poorly sampled
areas of spinosaurid anatomy, suggest that sympatry was present and potentially common in baryonychines and spinosaurids as a whole, and contribute to updated palaeobiogeographic reconstructions for the
clade.

It's unusual and very welcome when a scientist actually involved in the research writes a clear account
for non-specialists in the field. Naish is very good at this sort of thing.

I'm not familiar with Benton's 4th. Benton himself is an exalted "grey eminence" in the field, "OBE FRS FRSE",
and as such can emphasize and omit what he likes without much fear of argument. I like the tone of Naish's discussions when
he talks of the inevitable controversies that accompany research. Does Benton? As I say, I haven't seen his books.

I'm not familiar with Benton's 4th. Benton himself is an exalted "grey eminence" in the field, "OBE FRS FRSE",Despite his 65 years still very active in the field. His publication
list is impressive (and available as pdf's):

an entire field is mostly consensus, but sure, for example Benton pays attention to the 1,2,3 or 2,3,4 digit controversy in birds (box 9.2 on p.283).
