It's believed that large herds of these pig-sized <a href="http://dinosaurs.about.com/od/typesofdinosaurs/a/ceratopsians.htm">ceratopsians</a> roamed the plains and woodlands of middle Cretaceous Asia, where they were preyed on by hungry <a href="http://dinosaurs.about.com/od/typesofdinosaurs/a/tyrannosaurs.htm">tyrannosaurs</a> and <a href="http://dinosaurs.about.com/od/typesofdinosaurs/a/raptors.htm">raptors</a>. (See also <a href="http://dinosaurs.about.com/od/typesofdinosaurs/a/Protoceratops-Facts.htm">10 Facts About Protoceratops</a>.)<br />
As tiny as it was compared to later herbivorous dinosaurs, Protoceratops lay near the trunk of a mighty dinosaur evolutionary tree, giving rise to the giant ceratopsians of the late Cretaceous period--including such famous and familiar dinosaurs as <a href="http://dinosaurs.about.com/od/dinosaurbasics/a/triceratopshub.htm">Triceratops</a>, <a href="http://dinosaurs.about.com/od/herbivorousdinosaurs/p/centrosaurus.htm">Centrosaurus</a> and <a href="http://dinosaurs.about.com/od/herbivorousdinosaurs/p/styracosaurus.htm">Styracosaurus</a>. However, Protoceratops wasn't the most "basal" ceratopsian; that honor probably belongs to the much earlier <a href="http://dinosaurs.about.com/od/herbivorousdinosaurs/p/psittacosaurus.htm">Psittacosaurus</a>, if not an even earlier genus.<br />
Protoceratops has earned a place in the paleontology hall of fame for a rare fossil find: the <a href="http://dinosaurs.about.com/od/dailylifeofadinosaur/a/protoveloc.htm">tangled skeletons</a> of a Protoceratops and a <a href="http://dinosaurs.about.com/od/carnivorousdinosaurs/p/velociraptor.htm">Velociraptor</a>, who were presumably in mid-fight when they were both buried together by a sudden sandstorm.</div>Angela Choohttp://www.blogger.com/profile/10118884370136307665noreply@blogger.com0tag:blogger.com,1999:blog-2277485170649657675.post-57937477374645578042011-12-11T22:14:00.000-08:002011-12-11T22:17:29.404-08:00Stegosaurus<div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/-WnVda92cXvE/TuWcUrXjY9I/AAAAAAAAABo/Lv9Keo6LXjQ/s1600/Stegosaurus2.jpg" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" src="http://1.bp.blogspot.com/-WnVda92cXvE/TuWcUrXjY9I/AAAAAAAAABo/Lv9Keo6LXjQ/s1600/Stegosaurus2.jpg" /></a></div><br />

<div style="text-align: justify;"> Just say the word "tyrannosaur," and most people immediately picture the king of all dinosaurs, <a href="http://dinosaurs.about.com/od/carnivorousdinosaurs/p/tyrannosaurus.htm">Tyrannosaurus Rex</a>. However, as any paleontologist worth his pickaxe will tell you, T. Rex was far from the only tyrannosaur roaming the forests, plains, and swamplands of the <a href="http://dinosaurs.about.com/od/dinosaurbasics/a/dinosaurages_4.htm">Cretaceous</a> period (although it was certainly one of the biggest). From the perspective of a small, quivering herbivorous dinosaur, <a href="http://dinosaurs.about.com/od/carnivorousdinosaurs/p/daspletosaurus.htm">Daspletosaurus</a>, <a href="http://dinosaurs.about.com/od/carnivorousdinosaurs/p/alioramus.htm">Alioramus</a>, and a dozen or so other tyrannosaur genera were every bit as dangerous, and their teeth were just as sharp. </div><div style="text-align: justify;"> </div><div style="text-align: justify;"> As with other broad classifications of dinosaurs, the definition of a tyrannosaur (Greek for "tyrant lizard") involves a combination of arcane anatomical features and broad swathes of physiology. Generally speaking, though, tyrannosaurs are best described as large, bipedal, meat- eating theropod dinosaurs possessing powerful legs and torsos; large, heavy heads studded with numerous sharp teeth; and tiny, almost vestigial-looking arms. As a general rule, tyrannosaurs tended to resemble one another more closely than did the members of other dinosaur families (such as <a href="http://dinosaurs.about.com/od/typesofdinosaurs/a/ceratopsians.htm">ceratopsians</a>), but there are some exceptions, as noted below. (By the way, tyrannosaurs weren't the only theropod dinosaurs of the Cretaceous period; other members of this populous breed included <a href="http://dinosaurs.about.com/od/typesofdinosaurs/a/raptors.htm">raptors</a>, <a href="http://dinosaurs.about.com/od/typesofdinosaurs/a/ornithomimids.htm">ornithomimids</a> and feathered "<a href="http://dinosaurs.about.com/od/thedinobirdconnection/a/dinobirds.htm">dino-birds</a>.")</div>Angela Choohttp://www.blogger.com/profile/10118884370136307665noreply@blogger.com0tag:blogger.com,1999:blog-2277485170649657675.post-24849136109005568152011-12-11T00:10:00.000-08:002011-12-11T00:17:26.228-08:00Extinction of Animals<table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody>
