Darren,
sorry, I just went to the site and do not find that issue listed. What is the 
price?

At long last, the Purbeck volume is out. 

Milner, A. R. & Batten, D. J. (eds) 2002. Life and 
Environment in Purbeck Times. _Special Paper in 
Palaeontology_ 68, 268.

Ordering information should be available at www.palass.org 
The papers of interest are...

Evans, S. E. & McGowan, G. J. Lissamphibian remains 
from the Purbeck Limestone Group, southern England, pp. 
103-119.

Two salamanders - the new crown-group urodele 
_Apricosiren ensomi_and a batrachosauroidid-like form - 
are reported as is albanerpetontid material and the new 
discoglossid-like frog _Sunnybatrachus purbeckensis_ 
(Sunnydown Farm Quarry is an important Purbeck 
Limestone site). 

Salisbury, S. W. Crocodilians from the Lower Cretaceous 
(Berriasian) Purbeck Limestone Group of Dorset, southern 
England, pp. 121-144.

Of the 13 Purbeck crocodyliforms, only _Goniopholis 
crassidens_, _G. simus_., _G. (_Nannosuchus_) 
gracilidens_, _Pholidosaurus purbeckensis_ and 
_Theriosuchus pusillus_ are considered valid. Alas poor 
_Oweniasuchus_.... A tooth (preserved on the same slab as 
the _Parviraptor estesi_ Evans 1994) suggested to be 
referable to _Lisboasaurus_ is regarded as incertae sedis, so 
no evidence in the Purbeck for this genus.

Evans, S. E. & Searle, B. Lepidosaurian reptiles from the 
Purbeck Limestone Group of Dorset, southern England, pp. 
145-159.

This is a pretty valuable review of lepidosaur tooth 
morphology and terminology. The new scincomorph 
_Parasaurillus_ is named for material that Hoffstetter (1967) 
referred to Owen's (1854) species _Saurillus obtusus_ (the 
holotype lower jaw of which is lost) and the sphenodontians 
_Homoeosaurus_ and _Opisthias_ are present at 
Sunnydown Farm Quarry.

Norman, D. B. & Barrett, P. M. Ornithischian dinosaurs 
from the Lower Cretaceous (Berriasian) of England, pp. 
161-189.

This is the long-awaited redescription of _Iguanodon 
hoggii_ Owen 1874 - renamed _Camptosaurus hoggii_ 
herein - and _Echinodon_. Intriguingly Norman and Barrett 
note that the former assignment 'calls into question the 
affinities' of _I. fittoni_, _I. dawsoni_ and _C. depressus_. 
Good: it's becoming clear that most of the British stuff 
conventionally referred to _Iguanodon_ is not definitely 
referable to this genus.  _C. hoggii_ is compared 
extensively with the other camptosaurs (except 
_Draconyx_) and they also describe and figure some 
referred material including a femur, dorsal centrum, pedal 
phalanx and tibia. Some of this is from the Speeton Clay in 
Yorkshire. 

_Echinodon_ is treated to an extensive description and 
discussion (of course they favour the view that it is 
heterodontosaurid). A tooth and one caudal vertebra from 
Purbeck represent the only evidence for ankylosaurs and 
reported stegosaur material (Benton and Spencer 1995) is 
considered to probably represent indeterminate sauropods. 

Milner, A. C. Theropod dinosaurs of the Purbeck Limestone 
Group, southern England, pp. 191-201.

The dromaeosaurid identity of _Nuthetes_ is established 
based on denticle and tooth morphology features and a 
partial right metatarsal III (254mm long) is also suggested 
to be from a dromaeosaur (though a possible 
oviraptorosaurian identity is also considered... this is ruled 
out because of chronological/biogeographical evidence but 
this predates Naish and Martill 2002 on _Thecocoelurus_). 
Milner also says that _Nuthetes_ is the first dromaeosaur 
reported from Britain; this might indicate that she disagrees 
with the proposed dromaeosaurid identity of 
_Ornithodesmus_.

Ensom, P. C. Vertebrate trace fossils in the Purbeck 
Limestone Group of southern England, pp. 203-220.

Tracks, coprolites and so on.

Ensom, P. C. Reptile eggshell, tiny vertebrate remains and 
globular calcified cartilage from the Purbeck Limestone 
Group of southern England, pp. 221-249.

Some of the eggshell fragments might be from sauropods 
and there are also various tiny dinosaur teeth, some of 
which appear to be from a form with _Camarasaurus_-like 
teeth. 

Sigogneau-Russell, D. & Kielan-Jaworowska, Z. Mammals 
from the Purbeck Limestone Group of Dorset, southern 
England, pp. 241-255.

A detailed review covering the multituberculates, 
docodonts, 'tricodonts' (including mention of a new large 
form something like _Austrotriconodon_ from Campanian 
Argentina), dryolestoids, peramurids and so on. _Tinodon_ 
is reported from Sunnydown Farm (its first record outside 
of the Morrison) but of course this has by now been 
described (as _T. micron_) by Ensom and Sigogneau-
Russell (2000: _Cret. Res._ 21, 767-779).

If you a Pal. Ass member this volume is of course available 
at a reduced price relative to its 'shelf' price (£66).
