ilzho Posted January 19, 2017 Share Posted January 19, 2017 I found these at Aurora Phosphate mine. Are these sperm whale teeth? I remember as a kid I found these and all the adults on the bus (as everyone is showing off their finds) gave me ugly looks, hahaha. It was all in good fun, but at that time I knew I found something cool. Ahh the good ol days....... Link to comment Share on other sites More sharing options...
FossilDudeCO Posted January 19, 2017 Share Posted January 19, 2017 I would say yes, but I am no expert on Whale Teeth. Try... @ynot or @sixgill pete Link to comment Share on other sites More sharing options...
ynot Posted January 19, 2017 Share Posted January 19, 2017 They are whale teeth but I am unsure if they are sperm whale. @Boesse will know for sure. Tony 3 Darwin said: " Man sprang from monkeys."

Boesse Posted January 20, 2017 Share Posted January 20, 2017 These are teeth of the "Kogiopsis floridana" morphotype, figured above from Whitmore and Kaltenbach 2008 (Lee Creek IV). 5 Link to comment Share on other sites More sharing options...
ilzho Posted January 29, 2017 Author Share Posted January 29, 2017 Does anyone know if there is a drawing of the "Kogiopsis floridana"? Thanks Link to comment Share on other sites More sharing options...

ilzho Posted January 29, 2017 Author Share Posted January 29, 2017 Looking for a drawing of the whale, not the teeth. I realize there may not be one, but it would be cool to see what one might look like. Link to comment Share on other sites More sharing options...
-Andy- Posted January 30, 2017 Share Posted January 30, 2017 Kogiopsis is a pygmy sperm whale, so they are expected to look similar to extant sperm whales Extant pygmy sperm whale Orycterocetus, which might've looked similar to Kogiopsis Looking forward to meeting my fellow Singaporean collectors!

Boesse Posted January 30, 2017 Share Posted January 30, 2017 We don't really know what Kogiopsis is, if it's a kogiid, physeterid, or stem physeteroid; further, all we have is a mandible with some teeth, so we don't know what it looked like externally. 2 Link to comment Share on other sites More sharing options...

If anyone is wondering, take Boesse's word on this. He's one of the most knowledgeable member here on prehistoric whales. Looking forward to meeting my fellow Singaporean collectors!

abyssunder Posted January 30, 2017 Share Posted January 30, 2017 As Bobby said and it was described and illustrated in R. Kellogg. 1929. A new fossil toothed whale from Florida. American Museum Novitates 389:1-10 - see Tim's link. †Kogiopsis floridana Kellogg 1929 (sperm whale) " Kogiopsis, new genus DIAGNOSIS.-Skull unknown. Mandible incomplete, but symphysis estimated to comprise one-third of its length. In general conformation similar to corresponding portions of mandibles of Kogia, but differs in having broader symphysis, six instead of eight teeth on symphysial portion of ramus, alveoli not extending over so far on lateral surface of ramus, and in addition is much larger. Rami firmly ankylosed in region of symphysis; dorsal surface of symphysis rather broad and flat; lateral surfaces of rami slope to mid-line of ventral face of symphysis. Large alveoli located on upper outer edge or angle of mandible. Ten teeth in each mandible, of which six are lodged in symphysis. Teeth long (3 to 4 inches in length), somewhat curved, with small crowns, without distinct neck, and rather closely spaced. Outer surface of cement wrinkled and ornamented with coarse longitudinal grooves. Outer surface of internal cone of dentine encircled by fine ridges. Kogiopsis floridana, new species TYPE.-Amer. Mus. No. 20470. Symphysial portion of lower jaws, with eleven teeth in place. Collected by W. D. Matthew in 1924.HORIZON AND LOCALITY.-Land pebble phosphate deposits. American Cyanamid Company pit at Brewster, Polk County, Florida.
