yes when you get the national dex
There are only 150 of them
Pokemon 150 is Palkia, the Space Pokemon. You can find it at Spear Pillar.
In the sinnoh dex of Pokemon Diamond/Pearl, they allow 150 Pokemon, and in the sinnoh dex of Pokemon Platinum, they allow 210, but in the national dex they allow 493 Pokemon
