摘要
The systematic placement and content of the family Mecochiridae are briefly reviewed. Meyeria houdardi (Van Straelen, 1936) (Gault facies, Albian, East of the Paris Basin and Pays de Bray) is revisited and described in detail. Previously unknown rostrum, hepatic furrow, endopleurites, posterior abdominal somites and caudal fan are described. A ? Meyeria sp. (lowermost Cenomanian, Charente-Maritime) is described. Both species were seemingly burrowers, deposit and suspension feeders and lived on sheltered, quiet, clayey sedimentary bottom, in marine domain.
