DIJ. J. ^V. DAWSOX OS KRKC'V TREES CONTAINING ANIMAL 



If we inquire as to the footprints of laro-er size inchuled In tlie geiuis Sauropu.'^, we 

 know by the evidence of osseous remains that some large Batrachians inliabited the 

 areas of eoal depoaitioi\ in Ni.va Scotia. ^NFore especially Baphetes plankeps (OwEx) 

 must have been an animal of sulHcient dimensions to have produced footprints like 

 those of Saiiro}' IIS nuipiifer. A second species of Jiaphclcs is probably indicated l)y a 

 jaw-bone found at the South Juggins, and which I have named provisionally B. mihor 

 The J^osduruii Ja'(//((/i"x of ^I aksii must liave been a large animal; but we do not 

 yet know if it was capable of walking on the land. 



On the whtile, the evideiu-c of footin-ints serves to indicate that both Lahip-iniho- 

 donthi and Micriisiiiinn exi>ti'd in Nova Scotia throughout the Carboniferous Period, 

 and that very man v of the larger and important species still rejnain to be discovered. 

 It seems rcmarkabU' that, nhilc remains of Fishes are so abundant in the carboniferous 

 shales of Nova Scotia and New Brunswick, nothing is as yet known as to the more 

 atiuatic tvpcs of Ijatrachiaiis found so abundantly in the carboniferous strata elsewhere. 

 This may either indicate a local paucity of these creatures, or may be a mere accident 

 of preservation or discovei-y.
