Hi all, For a few months now, I occasionally go searching for shark/ray teeth in an old industrial area in Aruba. I found hundreds of smaller shark teeth (probably carcharhinus) and a handful of very cool & much larger teeth (likely otodus angustidens). This morning, I went walking the dogs there and stumbled upon a chunk of a much larger tooth! Could it be the megalodon? it could be a larger specimen of an O. Angustidens but the proportions are not quite the same… I'll let the experts judge for themselves. The (almost) complete O. Angustidens tooth in the middle is 2’1 inches (5,3 cm) long.

Pleistocene-Holocene distribution of large Eagles and Hawks (Accipitridae) on island environments
Joseph Fossil posted a topic in General Fossil Discussion
After doing some research a few weeks back on the distribution of the extinct Haast's eagle (Hieraaetus moorei), I discovered there was a much larger array of large Accipitridae on island environments than I previously realized (the result of island gigantism) during the Pleistocene-Early Holocene. Sadly, many of these animals are now extinct asa result of direct human hunting or hunting of their food sources by the early-late Holocene. I've decided to make a quick list of all those I've identified, which hopefully can demonstrate the diversity these magnificent animals had during the Pleistocene-Early Holocene. Let me know if I forget any examples. New Zealand - Haast's eagle (Hieraaetus moorei) (Pleistocene-late Holocene (At least 1450 A.D.)) Eyles's Harrier (Circus teauteensis) (Pleistocene-Holocene) Crete - Cretan subspecies of the Golden Eagle (Aquila chrysaetos simurgh) (late Pleistocene) Cuba - Gigantohierax suarezi (Holocene) (0.012-0.005 years ago) Gigantohierax itchei (Holocene) (0.012-0.005 years ago) Borras's eagle-hawk (Buteogallus borrasi) (Pleistocene-early Holocene) Bahamas - Bahamian Titan Hawk (Titanohierax gloveralleni) (Pleistocene-Holocene) Hispaniolan Titan Hawk (Titanohierax sp.) (Pleistocene-Holocene) New Caledonia - Powerful goshawk (Accipiter efficax) Madagascar - Malagasy crowned eagle (Stephanoaetus mahery) (Pleistocene-late Holocene (at least 1500 A.D.)) Hawaii - Haliaeetus sp. (either new Haliaeetus species or a subspecies of the extant White-tailed Eagle (Haliaeetus albicilla)) (Pleistocene-Holocene) What do you guys think?- 1 reply
