BARYONYX WALKERI 
| particular Mr Frank Datson, Mr Derek Sturt and their staff for the assistance 
| they gave us in collecting the specimen and for their cheerful sufferance of the 
) inconvenience we must have caused them. We should like to express our 
» gratitude to the dozens of people, both Museum staff and others, who helped 
us to collect the skeleton; to the Museum photographers who recorded the 
excavation, in particular Colin Keates and Phil Crabb, who also prepared the 
photographs for drawing and for publication; to Chris Jones of the SEM unit, 
who helped produce the scanning electron micrographs used in this paper; 
and to Alison Longbottom, for general assistance in our research. John 
| Holmes made the model of a Baryonyx carcase (Fig. 49) and Ms Jess Wallace 
} made the drawings for this paper. We also thank Mr John Sibbick for 
generously permitting the reproduction of his painting of Baryonyx (Frontis- 
piece). Our greatest debt of gratitude, however, is to Ron Croucher, formerly 
of the Museum’s Palaeontology Laboratory, who, together with William 
Lindsay, Lorraine Cornish, Adrian Doyle, David Gray and other members of 
staff, devoted years of patient, skilful work to the development of the 
skeleton. For information and discussion on the taphonomy we are especially 
obliged to Dr Peter Andrews, and our stratigraphical advisers (both special- 
ists on the Smokejack’s succession) were Philip Palmer and Andrew Ross. Dr 
David Norman (Sedgwick Museum, Cambridge) kindly confirmed the iden- 
tity of associated Jguanodon remains. Dr Ed Jarzembowski (Maidstone 
Museum and Art Gallery) and Mr Julian Porter (Bexhill Museum) provided 
details of tooth crowns from other Wealden localities. Finally, we should like 
to acknowledge the generous help given us by Dr Philip Currie (Royal Tyrrell 
Museum, Drumheller, Alberta), Drs Gene Gaffney and Mark Norell (Ameri- 
can Museum of Natural History, New York), Dr Jack Horner (Museum of the 
Rockies, Bozeman, Montana), Dr Nicholas Hotton III and Mr Michael Brett- 
Surman (United States National Museum, Washington D.C.), Dr Christopher 
McGowan (Royal Ontario Museum, Toronto), Dr James Madsen (Dinolab, 
Salt Lake City, Utah), Dr Wade Miller and Mr Kenneth Stadtman (Brigham 
oung University Museum of Earth Sciences, Provo, Utah), Drs Kevin 
Padian and Samuel Welles (Museum of Paleontology, Berkeley, California) 
and Mr Glen Ungerman (University of Utah Museum, Salt Lake City) in 
making comparative studies in their respective institutions.
