237 MYA would not be a time where you would want to go swimming. Yes, the water was nice and warm, however it was home to a less than ideal swimming partner, the Shonisaurus. This was a meat eating ichthyosaur like no other, not because it was particularly fast or intelligent, rather it was huge, huge enough to be considered the largest marine reptile to have ever existed!
