†Otodus megalodon (Agassiz 1843) ♂ (Pisces Chondrichthyes Lamniformes †Otodontidæ)

[†Otodus Agassiz 1838: †11 spp]

23.0-2.6 mya, 24.3 m × 5E4 Kg ℮

Currently there is near unanimous consensus that megalodon shark belongs to †Otodontidæ; in 2016, †Carcharocles was treated as invalid and lumped within †Otodus in order to preserve monophyly, with †Megalolamna as its sister clade. Cfr. note¹ over the above image².

NOTES

1. Scale ≅ 1:64; 5 m = 300√p; 1√p = 1/96" ≅ 1.67E-2 m.
