Re: Dinosaur formations and time.
<<Hello to all, I want to know all mesozoic formation and the age...please
help me to complet the list:
Jagua Formation ... Oxfordian - Cuba>>
Without checking:
Hell Creek Formation ... Maastrichtian, USA
Lance Formation ... Maastrichtian, USA
Laramie Formation ... Maastrichtian,
Allen Formation ..., probabaly Campanian or Maastrichtian, Argentina
Nemegt Formation... Campanian, Mongolia
Barun Goyot Formation ... Campanian, Mongolia
Judith River Formation... Campanian, Montana
Kaiparowits Formation... Cretaceous (I've forgotten when!), Utah
Djadochta Formation ..., Campanian, Mongolia
Now I'm running out of time
Arundel Clay ... Lower Cretaceous, Maryland or somewhere in that area.
Hastings Beds ... Wealden, Lower Cretaceous, Hastings in Sussex, UK
Wealden Group ... Lower Cretaceous
Wessex Formation ... Isle of Wight, it's the local equivalent of the Wealden
Purbeck Beds ..., Dorest, UK, lowermost Cretaceous (I'm a Dorset fossil
myself!)
Kimmeridge Clay , Dorset, UK, Kimmeridgian (below the Portlandian and, above
that, the Purbeck beds)
Tendaguru Formation ... Tanzania, Kimmeridgian
Morrison Formation, various US States including Wyoming, age somewhat
disputed, popularly cited as Kimmeridgian
Oxford Clay... Oxfordshire, UK, Oxfordian
Daohugou Beds ..., poorly resolved, assingnments include Middle Jurassic to
Lower Cretaceous, and all points inbetween, Inner Mongolia. China
Kayenta Formation ... Arizon, Lower Jurassic
Kota Formation ... India and poorly resolved, Lower Jurassic is popularly
cited, but at least part is probably Middle Jurassic
Portland Formation ... Dorset, UK, Tithonian (directly beneath the
Purbeckian
Time's up!
