[dinosaur] Alternate Mesozoic Epochs

I'm attempting to make a geologic timescale incorporating different subdivisions and I've come across some older Mesozoic epoch terms like Scythian, Lias, Neocomian, Senonian, etc. Does anyone know what classification system they belong to and what ICS stages they correlate to? If someone could provide a reference/paper for these epochs that would be great, too.
