Third story mission where you first go to the Dreadnaught. Progress through the mission up until the disappearing platforms that require you ghost. Head directly across while pulling your ghost out and enter the first room where you have to scan the worm on the ground. To your right there is a couple of pillars that are tilted, the calcified fragment will be at the top of these.
16. Calcified Fragment XVI
Third story mission where you first go to the Dreadnaught. Once you land, at the very start you are on a little walkway that sticks out from the Dreadnaught. Immediately drop down to your left under the little purple/red/maroon banners and onto the dirt pile and hop over it a little bit, the calcified fragment will be right there.
17. Calcified Fragment XVII
Third story mission where you first go to the Dreadnaught. Once you land, continue all the way to the end of the first area (skipping the door you're meant to enter) and head right down a little hallway. The calcified fragment will be on the left.
