Re: [dinosaur] Mammal recovery after K-Pg extinction happened fast + NOVA Rise of the Mammals

The Denver Museum of Nature and Science website has posted new material
about the find:

https://urldefense.proofpoint.com/v2/url?u=https-3A__coloradosprings.dmns.org_&d=DwIFaQ&c=clK7kQUTWtAVEOVIgvi0NU5BOUHhpN0H8p7CSfnc_gI&r=Ry_mO4IFaUmGof_Yl9MyZgecRCKHn5g4z1CYJgFW9SI&m=d2gCv_I6dntRoPxB7mkTMH59e1JFn24XkwF4KXIDsuE&s=M0CPtneq3n5MNEfKNa_IIZb92SGtaqucNP-ZEh9w1Ws&e= 

However, when you click on the Mammal gallery, you get a wrong etymology:

https://urldefense.proofpoint.com/v2/url?u=https-3A__coloradosprings.dmns.org_the-2Dmammals_&d=DwIFaQ&c=clK7kQUTWtAVEOVIgvi0NU5BOUHhpN0H8p7CSfnc_gI&r=Ry_mO4IFaUmGof_Yl9MyZgecRCKHn5g4z1CYJgFW9SI&m=d2gCv_I6dntRoPxB7mkTMH59e1JFn24XkwF4KXIDsuE&s=o26KdRNoS8-kaoIxZiaBdpvD982FlbAoJbITzfiZsyo&e= 

Taeniolabis means "banded incisor" (not "ribbon lips" (from Wikipedia it
seems), which makes no sense!). Cope used the Greek word labis "tongs,
forceps" to refer to incisor teeth.  The name Taeniolabis is referring the
band of enamel on the teeth, just as Taeniodonta Cope "banded teeth" refers
to "incisors present two bands of enamel, an anterior and a posterior."


Greek tainia "band, fillet, ribbon"
+
Greek labis (labidos) "tongs, forceps" > Cope: "incisor (tooth)" (NOT to be
confused with unrelated Latin labium "lip"!!)


***
Note as well:
Labidosaurus Cope  "incisor lizard": "Internal incisor much enlarged,
conic, acute, and directed backwards"
