My beliefs about Spinosaurus and Carcharadontosaurus.

This is based of ideas I have put together. I do ask (no names because I dont know everyone) for no agressive arguements in the comments, but only feedback on ideas that can make my idea better.

Now to buisness.

I believe that Spinosaurus and Carcharadontosaurus didn't fight when they spotted one another rather, One saught the other out. I believe that Carchara saught out spino for a few reasons that would be understandable.

1: Water. Spino lived by water pretty much their entire lives. So if a Carchara couldn't find water, he/she may find a spino because it will lead it to water.

2: Food. Not eating the Spino, but everything else. If Spino goes to a river and Carchara follows. He will have almost no reason to leave because where there is water, there is food. Every living thing needs water. So Carchara could stay around the area, out of Spinos way.

But even if the Spino and the Carchara met, I think Spino would just bluff him off because Carchara came to HIS terrotory on purpose and knows it. And if you piss off the host, you get kicked out of the house. Or they would just growl or hiss and go away from eachother.

But Spino would use Carchara as well. I think he would use him to keep other predetors out of the area. Being that two massive animals in the same area would make them too nervious to stay.

Overall, I believe Spino would be passive aggressive to Carcharadontosaurus unless the situation demanded and that Carcharadontosaurus used Spino as much as Spino him him/her.
