Molten from the golden teeth of our ancestral king, polished with crystal denticles of the lunar presence and tempered in the tears of Snoot Peak. The staff of the new cycle has finally been refined for its destined purpose!

I’m excited to share our new paper, out now in . We used scales (denticles) preserved in coral reef sediments to reconstruct the pre-exploitation baseline of a reef shark community in Caribbean Panama. https://t.co/Sbl0sOm0J2 (1/18)
