Extinction extinction This is the collection of events in which a species becomes extinct. Such events would presumably include both the final cause of the extinction and the dying off of the last members of the the species.

Extinction

http://en.wikipedia.org/wiki/Extinction The collection of all <a href="http://sw.opencyc.org/concept/Mx4rvVj5IJwpEbGdrcN5Y29ycA" class="cyc_term">DestructionEvent</a>s in which something <a href="http://sw.opencyc.org/concept/Mx4rvVj27ZwpEbGdrcN5Y29ycA" class="cyc_term">PartiallyTangible</a> is destroyed via physical means. Examples include natural disasters (cf. <a href="http://sw.opencyc.org/concept/Mx4rwP1YzJwpEbGdrcN5Y29ycA" class="cyc_term">DisasterEvent</a>), <a href="http://sw.opencyc.org/concept/Mx4rvVisLpwpEbGdrcN5Y29ycA" class="cyc_term">KillingByOrganism</a>s, and dissassemblings (cf. <a href="http://sw.opencyc.org/concept/Mx4rwKaW2ZwpEbGdrcN5Y29ycA" class="cyc_term">TakingApartAnArtifact</a>). For cases where at least some portion of the thing destroyed becomes incorporated into a new created thing, see the more specialized <a href="http://sw.opencyc.org/concept/Mx4rvVibApwpEbGdrcN5Y29ycA" class="cyc_term">PhysicalTransformationEvent</a>.

TemporalObjectType temporal object type A specialization of <a href="http://sw.opencyc.org/concept/Mx4rvVirnZwpEbGdrcN5Y29ycA" class="cyc_term">ObjectType</a> (q.v.) whose instances are all and only those collections that are temporally object-like. A collection <code>COL</code> is temporally object-like just in case it generally holds that any proper purely temporal parts (see <a href="http://sw.opencyc.org/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA" class="cyc_term">timeSlices</a>) of an instance of <code>COL</code> is not itself an instance of <code>COL</code>. More precisely, a collection <code>COL</code> is an instance of <a href="http://sw.opencyc.org/concept/Mx4rvViq35wpEbGdrcN5Y29ycA" class="cyc_term">TemporalObjectType</a> just in case it satisfies the following: For any distinct <code>OBJ1</code> and <code>OBJ2</code>, if <code>(<a href="http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> OBJ1 COL)</code> and <code>(<a href="http://sw.opencyc.org/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA" class="cyc_term">timeSlices</a> OBJ1 OBJ2)</code>, then not <code>(<a href="http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> OBJ2 COL)</code>. For example, none of the proper time-slices of a <a href="http://sw.opencyc.org/concept/Mx4rvVjyV5wpEbGdrcN5Y29ycA" class="cyc_term">CalendarYear</a> is itself a calendar year. Likewise for <a href="http://sw.opencyc.org/concept/Mx4rvViYBpwpEbGdrcN5Y29ycA" class="cyc_term">TakingAStep</a>. So <a href="http://sw.opencyc.org/concept/Mx4rvVjyV5wpEbGdrcN5Y29ycA" class="cyc_term">CalendarYear</a> and <a href="http://sw.opencyc.org/concept/Mx4rvViYBpwpEbGdrcN5Y29ycA" class="cyc_term">TakingAStep</a> are both instances of <a href="http://sw.opencyc.org/concept/Mx4rvViq35wpEbGdrcN5Y29ycA" class="cyc_term">TemporalObjectType</a>. Conversely, a proper time-slice of a given <a href="http://sw.opencyc.org/concept/Mx4rvVisWZwpEbGdrcN5Y29ycA" class="cyc_term">Date</a> might itself be a <a href="http://sw.opencyc.org/concept/Mx4rvVisWZwpEbGdrcN5Y29ycA" class="cyc_term">Date</a> (e.g. an hour has minutes and seconds as time-slices); so <a href="http://sw.opencyc.org/concept/Mx4rvVisWZwpEbGdrcN5Y29ycA" class="cyc_term">Date</a> is not a temporal-object-type. See <a href="http://sw.opencyc.org/concept/Mx4rvVitN5wpEbGdrcN5Y29ycA" class="cyc_term">TemporalStuffType</a> for the disjoint notion of being temporally stuff-like.
