Not how scientists name things they go by which was named first and suchomimus was second so it would be changed despite popularity

1.Sucho was named before in 1997

2.Even I’d it is,Cristatusaurus is considered the Dubious one by most scientists

Then looks like Wikipedia was wrong hmm wonder who told me I should be able to trust it oh right you saurio

Only a few people consider Suchomimus dubious while many consider Cristatusaurus a nomen dubium

English I don't speak French or what ever you wrote also on Wikipedia it says possible so still could be separate as they said inconclusive evidence to support from the lack of remains

According to my fast search they were named the same year

I don't care who came first, I just care if they are synonyms. Is this like the Allosaurus/Saurophaganax controversy?

Yes

I don't know who to vote, I just clicked randomly

Most likely Cristatusaurus because of its size advantage.
