Voice type question

This might be a dumb question, but I don’t have a professional vocal teacher and don’t know too much about how to determine these sorts of things: What would a vocal range of G1 to D5 be considered? Most websites are telling me that’s a tenor range, but I’m not sure as the timbre and quality of my voice changes drastically throughout my range. My low notes are very deep and gravelly and bass-y while my high notes are very bright and sharp and sound like a mezzo range. The timbre changes a lot. Not sure if that’s normal for a voice range or what. Thanks
