You will find the Pokemon you can extract from fossils and other info in the link below.

List:
Helix Fossil - Omanyte
Done Fossil - Kabuto
Old Amber - Aerodactyl
Root Fossil - Lileep
Claw Fossil - Anorith

Plume Fossil - Archen

In HeartGold/SoulSilver, these Pokemon can be revived at the Pewter Museum of Science.
*= only obtainable in Generation V. HeartGold is Gen IV, so they cannot be obtained.

Answer 2

Any Pokemon from Gen. IV or lower but you need a DS Lite or the DS to send Pokemon from GameBoy games such as R/S/E.
