Yes, this isn’t terribly uncommon. Owen describes a belemnite with preserved hooklets here: www.jstor.org/stable/pdf/108360.pdf

I have seen numerous examples from the posidonia shale, and there is also one from the Nusplingen limestone that even has its beak and ink sac preserved: onlinelibrary.wiley.com/doi/full/10.1111/j.1502-3931.2009.00203.x

Belemnites aren’t common until the Lower Jurassic, but there are also examples of Triassic cephalopods with preserved arm hooks: www.sciencedirect.com/science/article/pii/S1871174X07000601?via%3Dihub
