Marsh—festoration of European Dinosaurs. 407 
Art. XLVI.—Lestoration of Some European Dinosaurs, 
with Suggestions as to their Place among the Rurriuia ;* 
by O. C. Marsw. (With Plates V-VIII.) 
For several years, I have been engaged in investigating the 
Dinosaurs of North America, where these extinct reptiles 
were very abundant during the whole of Mesozoic time. 
The results of my study have been published from time to 
time, and I have already had the honor of presenting some of 
these to the British Association. In carrying out this investi- 
gation so as to include the whole group of Dinosaurs, wher- 
ever found, and bringing all under one system of classification, 
it has been necessary for me to study the remains discovered 
in Europe, and I have made several visits to this country for 
that purpose. | 
In comparing the forms known from the two continents, 
certain important differences as well as some marked resem- 
blaneces between the two have been observed, and placed on 
record. In concluding my investigations of the North Ameri- 
ean forms, I have fortunately been able to make restorations 
of the skeletons of quite a number of very complete type 
specimens, and this has proved a most instructive means of 
comparing those from different horizons, and of different 
groups, among the known Dinosauria of America. 
The success of this plan rendered it very desirable to extend 
it, if possible, to the best-known forms of European Dinosaurs. 
This I have been enabled to do in a few instances, and the 
main object of the present paper is to lay.these latest results 
before you. 
In approaching the subject of European Dinosaurs, and 
especially those of England, where the study of the group first 
began, I am well aware that I am on delicate ground, since 
many and various opinions have been expressed in regard to 
the nature of the remains here discovered, and particularly as 
to the form and appearance during life of the animals they 
represent. I may, perhaps, be permitted, in this connection, 
to say, what has often occurred to me, that the Dinosaurs 
seem to have been rather unfortunate, and to have suffered 
much from both their enemies and their friends. Many of 
them were destroyed and dismembered long ago by their nat- 
ural enemies, but, more recently, their friends have done them 
further injustice in putting together their scattered remains, 
and restoring them to supposed life-like forms.
