Appalachia (Mesozoikum)

Selama kebanyakan dari kala Kapur Akhir (100.5 hingga 66 juta tahun lalu), bagian timur dari Amerika Utara membentuk sebuah massa daratan yang disebut Appalachia (dinamai setelah Pegunungan Appalachia). Appalachia merupakan sebuah massa daratan berupa pulau yang terpisah dari Laramidia di barat oleh Lajur Laut Interior Barat, karena berbagai faktor seperti aktifitas tektonik dan fluktuasi ketinggian air laut selama hampir 40 juta tahun.^[1]^[2]
