154 MESOZOIC FOSSILS FROM THE PALMER RIVER, QUEENSLAND. 
the oolitic appearance of the rock is most striking. 
character of the Ammonite is even older. But, on the other hand, 
the species of Crrioceras, the shelly matter having nearly disap- 
peared, are fossils of quite another horizon, probably like those of 
the Flinders River. Neocomian or Lower Cretaceous: 
matrix has a different aspect, and the shells are fresh and new 
looking. How are we to account for this mixed fauna? Tf the 
fossils were associated in the same strata, it would be very 
puzzling. Seeing, however, that they are found as nodular masses
