As soon as you show me a picture of a dinosaur that better meets each of the descriptors. However, Job doesn't say the tail looks like a cedar, or is shaped like a cedar, or is large or as strong as a cedar, only that it bends or sways like a cedar.

No, you are the one that is reaching.
The ‘Bronto’ had a tail shaped like, and as large as a cedar tree. (actually, they still do according to people in the northern Congo)
