RE: One last question about Iguanodon

> Material: Skull, mandible & vertebrae
> Size: 6-7m long|1.8m @hips|1.5m tons

I'm not sure about the age for the Utah material (and if it's genuinely I.
lakotaensis), but the Lakota Formation, from which the South Dakota material
originates, is Barremian in age (at least that's the most recent date I've
seen). Hence, it is a little bit older than the dates you give (and more in
line with the age of the other Iguanodon species).

Best wishes,

Andy
