Abstract
An account is given of new, well-preserved, deep-bodied holostean fishes (family Semionotidae) from the continental Lower Jurassic, India. A new genus, Paradapedium, has been erected with Dapedium egertoni Sykes 1853 as type-species. New specimens are assigned to P. egertoni. The validity of Tetragonolepis oldhami Egerton 1878 is supported but T. analis and T. rugosus are found to be indeterminable. The age and distribution of deep-bodied semionotids is discussed. The evidence from the fossil fishes is in favour of a Liassic age for the Kota Formation. Knowledge of freshwater actinopterygians is improved.
