Crednetia basinervosa (
Hollick),
C. elegans (Hollick),
C. inordinata (Hollick),
C. intermedia (Hollick),
C. mixta(Hollick), and
C. truncatodenticulata (Bell) have all been identified as
junior synonyms of the
platanaceous species
Pseudoprotophyllum boreale. The species
Credneria grewiopsoides (Hollick),
C. longifolia (Hollick) and
C. spatiosa (Hollick) from the
Cenomanian Melozi and
Kaltag formations along the
Yukon River in Alaska are also possibly representatives of
Pseudoprotophyllum boreale, but the known fossil material for the species was considered too incomplete to make a determination. ==References==
