Abstract

There are discussed various general considerations entering into palacontological study of the problem as to whether the early evolution of fishes took place in fresh or salt water. Opposite conclusions as to the typical habitat of Silurian fishes have been reached by the author and Grovl on American evidence, on the one hand, and Gross, mainly concerned with European material, on the other. An attempt is made to reconcile this difference. Part may be due to the very different histories of the two continents in Silurian times. Close examination of the stratigraphy of European fossil fish localities suggests that many deposits which are often regarded as marine are of continental or near-continental nature. It is concluded that the evidence, taken as a whole, points strongly towards fresh waters as the common Silurian fish habitat.
