This topic has been debated in depth for years and is far from easy to answer. The PHB can be interpreted in both ways and often is. The DMG errata specifically states that you retain your hit points for ploymorph yet some suggest that being a secondary source on spells this in itself is a mistake. The Rules of the Game articles state that your adjusted CON changes your hit points but some point out that this isn't official whereas others say it is. You are not going to get a consistant answer on this but remember that the CON change isn't always beneficial especially when you change into lower CON smaller animal forms or when the wildshape ends. Chose whichever you prefer. Anyone who suggests this is clear cut has either never seen the endless arguments on various boards about this or is being a bit sneaky and looking for supporters of their cause

Our group plays adjust hit points if that helps

For the other questions above, the druid in question is 7th level. The player was looking at dinosaurs as a possibility to transform into but should he be able to transform into one if he's never seen one? The wildshape ability says you can't transform into a polar bear if you've never been outside of the temperate forrest. So how can a DM determine if a dinosaur would be okay. Or a elk. Or a buffalo. Or a etc, etc, etc.
If the group starts at first you can probably work with the player at the beginning of the campaign to determine a reasonable starting list. If you start at later levels or only decide to do this at later levels I would house rule a knowledge nature check for each species of animal inc dinosaur with DC's set based upon your world. Unless it is out of context for your world I'd generally set the DC's fairly low as the HD limit keeps things balanced.
