Partly but much is historical vandalism. If the new emperor didn't like the previous emperor, they often had their likenesses smashed.

People generally live in flood pains (where rivers meet the ocean). These rivers bring in silt and things eventually get buried over long periods of time. Just like lakes eventually fill up with silt and become land again.

In the end it is just high parts of the Earth (eg mountains) eroding and the silt piles up in the lower places... Making high places lower and lower places higher

Unlikely but ships are made of wood, so unless they are overloaded when damaged, they still float, even if just barely above the waterline. They have been known to drift for many years sometimes. They are what you may read about as "ghost ships" which really are just floating wrecks

Fossils should preserve well though, right? Ivd be really really surprised if no fossils have been found in native archeological sites... I mean if you find a cool trilobite fossil or something... It would make a nice decoration...

Its not a puzzle. They took it apart. They know how to put it back together!

She must have been pissed when she lost the ring. Imagine if she lost it on her wedding night!

Tattoos are a type of branding

If we are talking about the same thing the water was emptied and they followed the tunnel, but it lead under a hotel or some other building which meant they couldn't excavate further

Not surprised by the performance though!

That's right. The unusual thing about the Vasa is you could walk the whole length of the gun deck upright. Previous designs you would need to bend over to walk past the crossbeams. It is this extra height that is blamed for the ship rolling over and consequently sinking
