Va viure durant les edats faunísticas d&amp;#039;inicis del [[Blanquense]], fa uns 4 millons d&amp;#039;anys, fins a inicis del [[Irvingtoniense]] (fa uns 1.2 millons d&amp;#039;anys).&lt;br /&gt;
&lt;br /&gt;
== Orige i evolució ==&lt;br /&gt;
Es considera generalment que &amp;#039;&amp;#039;Stegomastodon&amp;#039;&amp;#039; deriva de poblacions de &amp;#039;&amp;#039;[[Gomphotherium]]&amp;#039;&amp;#039; del Nou Món. El número d&amp;#039;espècies situades dins del gènero ha variat des de solament una única espècie vàlida, &amp;#039;&amp;#039;S. mirificus&amp;#039;&amp;#039;, a les set espècies que va classificar en el seu moment [[Henry Fairfield Osborn]] a través d&amp;#039;un model de “[[Ortogénesis|mutacions ascendents]]”: &amp;#039;&amp;#039;S. primitivus, S. successor, S. mirificus, S. chapmani, S. texanus, S. arizonae&amp;#039;&amp;#039; i &amp;#039;&amp;#039;S. aftoniae&amp;#039;&amp;#039;. Lucas &amp;#039;&amp;#039;et al&amp;#039;&amp;#039;., 2013 varen acceptar 3 [[cronoespecie]]s successives: &amp;#039;&amp;#039;S. primitivus, S. mirificus&amp;#039;&amp;#039; i &amp;#039;&amp;#039;S. aftoniae&amp;#039;&amp;#039;.&amp;lt;ref name=&amp;quot;:0&amp;quot;&amp;gt;{{Cite book|last=Lucas, Spencer G.|title=Taxonomy and evolution of the Plio-Pleistocene proboscidean &amp;#039;&amp;#039;Stegomastodon&amp;#039;&amp;#039; in North America.|oclc=798103439}}&amp;lt;/ref&amp;gt;&lt;br /&gt;

== Descripció ==&lt;br /&gt;
[[File:Stegomastodon.jpg|thumb|left|Recreació d&amp;#039;una manada de &amp;#039;&amp;#039;S. mirificus&amp;#039;&amp;#039;]]&lt;br /&gt;
L&amp;#039;espècie &amp;#039;&amp;#039;Stegomastodon mirificus&amp;#039;&amp;#039; és coneguda a partir de l&amp;#039;espècimen NMNH 10707, un macho d&amp;#039;aproximadament 30 anys d&amp;#039;edat, del com es va trobar la major part de l&amp;#039;esquelet. En vida, est hauria medit uns {{convert|2.6|m|ft|abbr=on}} d&amp;#039;altura, en un pes d&amp;#039;al voltant de {{convert|4.7|t|LT ST}}.&amp;lt;ref name=&amp;quot;proboscideans&amp;quot;&amp;gt;{{Cite journal | last1 = Larramendi | first1 = A. | year = 2016 | title = Shoulder height, body mass and shape of proboscideans | journal = Acta Palaeontologica Polonica | volume = 61 | doi = 10.4202/app.00136.2014 | s2cid = 2092950 | url = https://www.app.pan.pl/archive/published/app61/app001362014.pdf }}&amp;lt;/ref&amp;gt; De la mateixa manera que els elefants moderns, pero a diferència de molts dels seus parents més propencs, solament posseïa dos defenses o &amp;quot;claus&amp;quot;, els quals es curvaven cap a dalt i medien prop de 3.5 metros de llongitut. El cap alt i la robusta mandíbula sugerixen que tenien una forta mossegada vertical. Els molar de &amp;#039;&amp;#039;Stegomastodon&amp;#039;&amp;#039;&amp;#039; tenien un complex patró de crestes i proyeccions en forma de montículs, la qual cosa donava a l&amp;#039;animal una àmplia superfície de masticació, #lo que sugerix en conjunt, que era un pastador.&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt; A principis de l&amp;#039;época del Irvingtoniano, &amp;#039;&amp;#039;Stegomastodon&amp;#039;&amp;#039; va ser reemplaçat pel gènero de elefántido &amp;#039;&amp;#039;[[Mammuthus]]&amp;#039;&amp;#039;, el qual era presumiblement un pastador més eficient. Es pensa que el seu cervell pesaria al voltant de {{convert|11|lb|kg|sigfig=1|abbr=on}}.&lt;br /&gt;
&lt;br /&gt;
Els més recents #espècimen en el registre fòssil per a este gènero s&amp;#039;originen en [[Jalisco]], [[Mèxic]] i daten de 28&amp;amp;nbsp;000 anys abans del present,&amp;lt;ref&amp;gt;{{Cite journal|last1=Alberdi|first1=María Teresa|last2=Juárez-Woo|first2=Javier|last3=Polac|first3=Oscar J.|last4=Riera-Cabrales|first4=Joaquín|date=2009-02-01|title=Description of the most complete skeleton of &amp;#039;&amp;#039;Stegomastodon&amp;#039;&amp;#039; (Mammalia, Gomphotheriidae) recorded for the Mexican Clapix Pleistocene|journal=Neues Jahrbuch für Geologie und Paläontologie, Abhandlungen|volume=251|issue=2|pages=239–255|doi=10.1127/0077-7749/2009/0251-0239}}&amp;lt;/ref&amp;gt; encara que esta datació tardana és prop d&amp;#039;un milló d&amp;#039;anys posterior als últims #espècimen confirmats.&lt;br /&gt;
