So after following nizaar ibrahim's study in 2014 I learned that spinosaurus walked on four legs and it spend a lot of time in water being a good swimmer. But recently I saw that some new studies have been published and then some others and I have lost track so if someone could please inform me about the latest discoveries and tell me if spinosaurus was a good swimmer and if he walked on four it would be much appreciated.

The original article by Arden et al supported the aquatic adapation of spinosaurus.  However just published comments by Holtz and Hone point to insufficient data to make that claim    "Some Spinosaurs may have spent extensive time in water, but the data to support this is currently insufficient and other hypotheses for their behaviour also fit the available data."

 

They are the experts and their comments should indicate there are more unknowns than knowns when it comes to the Kem Kem, nothing new.

Here’s the current comparisons. Bones in red are the bones they actually have found

It's mainly the supposed quadrupedality that has been criticized. It also doesn't take Sigilmassasaurus into account as a separate species. So there are definite problems with the reconstruction. But right now it's still the most recent and likely mostly accurate reconstruction we have. Spinosaurus is still a very enigmatic creature.

That image from Scott Hartman also does not take the angle of the femur into account. He already addressed this.
