• 19:4019:40, 24 June 2013 diff hist +195 Reptile Pls. discuss b4 changing much of this para. It is result of consensus (see talk pg thru ~2013-06-24) after long negotiation re reader [mis]interpret. of 'extinct' & [mis]understdg of dinosaurs-->birds, mono/polyphyletic dino. defns,, simplifying, etc...

• 15:4815:48, 24 June 2013 diff hist +262 Mass–energy equivalence See recent Talk! Pls. don't revert entire but improve (undo if nec.) parts. Avg reader can understand topic w/out mastering other aspects of relativity; other clnup: E&m are (proportionate) properties of a system, not (circularly) of one another.

• 18:4718:47, 21 June 2013 diff hist +61 Reptile how's this as a compromise, per most recent talk? please try to edit into an alternative compromise rather than simply revert
• 17:5517:55, 21 June 2013 diff hist +901 Talk:Reptile →incorrectly {okay, controversially} states that the dinosaurs are extinct {edit: in the introduction unnecessarily and without citations}!: OK, drop the word pseudo but add traditional in place of non-avian
• 05:0005:00, 21 June 2013 diff hist −91 Reptile mercilessly simplifying my own previous edits on dinosaurs who can be considered extinct, but more specifically pseudoextinct
• 04:2504:25, 21 June 2013 diff hist +53 Reptile another language tweak on the birds and their pseudoextinct ancestor species
• 04:1004:10, 21 June 2013 diff hist −22 Reptile slight reword
• 04:0104:01, 21 June 2013 diff hist +193 Reptile non-avian theropods as a group are pseudoextinct because they have living descendents (whom you've explicitly excluded from group membership); any given subgroup or species is pseudoextinct if and only if it does not contain any ancestors of modern birds

• 22:5622:56, 20 June 2013 diff hist +29 Reptile Those dinosaurs who were the ancestors of modern birds aren't birds themselves, but aren't extinct either! We can define the birds as non-dinosaurs but that doesn't in itself make their ancestors extinct! Tag: Visual edit

• 21:3521:35, 20 June 2013 diff hist +379 Reptile Further clarification of parenthetical that User:Peter M. Brown added in lead in response to the most recent Talk: Acknowledge (but don't endorse) that SOME scientists don't exclude birds from dinosauria definition.
