The tallest dinosaurs were brachiosaurid sauropods; they had front legs that were longer than their back legs and had a giraffe-like stance. They were gigantic, slow moving, tiny-headed, cow-like plant-eaters from the late Jurassic and the Cretaceous period. They had very long necks which were held upright and were useful for reaching wide (and tall) swatches of vegetation. The lengthy neck was counterbalanced by a massive tail. These sauropods are among the largest land animals ever discovered: \n\n1.Sauroposeidon(Wedel, Cifelli & Sanders vide Franklin, 2000), a newly-found brachiosaurid from Oklahoma, +60 tons, 60 feet tall. \n\n2.Ultrasauros (Jensen vide Olshevsky, 1991) - 100+ feet long (30 m), +80 tons \n\n3.Brachiosaurus (Riggs, 1903) - about 85 feet long (26 m), 40 feet tall, and weighed 70-80 tons

Crocodiles or Alligators are the obvious answers... don't forget the Komodo Dragon either, they're a bit on the old side too!

Whoa! slow down, there is fossil evidence a transition from reptiles and birds. Most famously Archeopteryx with reptilian skull, teeth, digits, claws, vertebrae, sternum, ribs, pelvis, tail, and mainly unfused bones, and a few bird traits like a wishbone, wings and feathers!! In older sediments, there are theropod dinosaurs with skeletal similarities to Archeopteryx. In younger sediments, there are several fossils with more birds-like traits, such as Sinornis and Shenzhouraptor and dozens more (wikipedia "fossil birds").\n\nFossils of scales and feathers are very very rarely preserved. Imprints of the Archeopteryx feathers are only preserved because the fossils are embedded in very rare, very fine limestone that used to be used in lithography. It is unreasonable to demand fossil evidence of a transition between scales and feathers. That said, there are several theropod fossils with feathers that have been recently discovered in a fine Chinese deposit, things like Sinosauropteryx, Caudipteryx and Beipiaosaurus.\n\nBut sure, every detail of the the transition from reptiles to birds isn't documented. Other than demanding an excessive amount of evidence, I really don't know what arguments you can use, I don't think there are any true ones. But you might find some convincing sounding ones on Creationist propaganda websites. It depends on your audience.

There are two basically different types of saber-tooth carnivores. Both are characterized by their extremely enlarged canine teeth. There are placental saber-tooth "tigers" that looked more or less like felids. The typical saber-tooth "cats" belong  to genus Smilodon. They were large carnivores but not as agile as cats, they were probably ambush-hunters.\nThis is the skeleton:\nhttp://www.dinosoria.com/mammifere/smilodon_002.jpg\nand this is a reconstruction (there are many that differ):\nhttp://www.abc.net.au/beasts/factfiles/primary_ff_displays/smilodon_1.jpg\n\nThe scimitar cat, represented by genus Homotherium, had similar appearance, but with shorter canines.\nThis is its skull:\nhttp://www.bluelion.org/images/BC_06_Homotherium_crenatidens.jpg\nThis is a reconstruction:\nhttp://www.paleocraft.com/images/homotherium.jpg\n\nThese animals inhabited North America during the Tertiary, and Smilodon spread to South America too. \n\nIn addition, there were also marsupial sabertooth mammals, represented by genus Thylacosmilus. These were convergent (evolved independently) and in their case, the enlarged canines were accompanied by the enlarged lower jaw. They were smaller than the placental forms.\nThe skull:\nhttp://www.caspercomsci.com/images/caspercollege/tn_FossilThylacosmilus_Atrox_jpg.jpg\nThe reconstruction:\nhttp://www.paleocraft.com/images/thylaatrox.jpg

Apatosaurus, often mistakenly refered to as Brontosaurus, is a genus of sauropod dinosaurs that lived about 140 million years ago, during the Jurassic period. They were some of the largest land animals that ever existed, about 4.5 metres (15 feet) tall at the hips, with a length of up to 25m (80 feet) and a mass up to 35 metric tonnes (40 tons). However, the Argentinosaurus was even larger.\n\nThe cervical vertebra and the bones in the legs were bigger and heavier than that of Diplodocus, but they both had the long neck and tail. The skull was first identified in 1975, a century after it got its name. The Apatosaurus had a claw on its hand, but only the thumb. Scientists have a theory about the tail being lifted perhaps a meter above the ground. It would prevent the dinosaur from stomping on it, and put the tail out of reach of predators.\n\n\nIn 1877, Othniel Charles Marsh published notes on his discovery of the Apatosaurus, and then in 1879 described another, more complete dinosaur — the Brontosaurus. In 1903, it was discovered that the apatosaur was in fact a juvenile brontosaur, and the name Apatosaurus, having been published first, was deemed to have priority as the official name; Brontosaurus was relegated to being a synonym. The name was not formally removed from the records of paleontology until 1974.

The biggest dinosaur is probably ultrasauros. We only have a few bones of this late Jurassic (140 million years ago) plant-eater from Colorado, but the bones show an animal who was six-stories high and may have weighed more than 50 tons. A four-legged plant-eating dinosaur found recently in Argentina, argentinasaurus, may have been even heavier than ultrasauros. If it was a brachiosaur like ultrauros then it probably was the biggest, but if it was a titanosaur, another kind of big plant-eater common in South America, it wouldn't have been so bulky.

Dinosaurs were very abundant, I couldnt swear that they were the MOST abundant vertebrate.

i think the crocodiles were the predominant carnivores in Antarctica in prehistoric times. But not now

To my knowledge the Bible doesn't mention anything about dinosaurs.  I've read about donkeys and giants, but no dinosaurs.  I figure I'll just ask Jesus about them when I get up there.

T. rex (Tyrannosaurus rex) was a large, meat-eating therapod dinosaur that lived during the late Cretaceous period of the Mesozoic era (about 70 to 65 million years ago).\n\nThere is no question that it ate meat, with huge steak-knife like teeth, binocular vision and other adaptations, but paleontologists have argued over whether or not it was a scavenger or active predator.\n\nMany of the proponents of each theory seem to forget that very very few animals are completely either/or.\n\nIn modern times, hyenas are considered scavengers while lions are generally considered top predators.  However, hyenas quite often kill their own prey, coopertating to take down wildebeest or zebras by themselves.  And lions often chase the hyenas off their kills, and scavenge the meal themselves.\n\nSo T. rex could indeed have been an active predator, hunting down or ambushing prey, but also could have been a scavenger, tracking down dead dinosaurs with its keen sense of smell, and it would have been well equipped to drive off almost any other predator that was already at the kill.  Even something as formiddable as a pack of Deinonychus probably would have backed off when T. rex came charging over the hill.\n\nThe fact that T. rex shows adaptations that could have been useful for either lifestyle says to me that they were probably flexible.  They may have acted primarily as scavengers in an area where other predators were common, but would have been able to become the dominant predator in other regions.  \n\nAnimals tend to be more complex than simply either/or statement.  Especially large, adaptable animals.  I think it's likely that T. rex was a predator in some regions, under some circumstances, and in other regions, with different circumstances it was primarily a scavenger.  Even the same animal may have changed its habits over the course of the year as it moved to different regions.

Never heard of a one-clawed dinosaur... one that has a single big claw is velociraptor. Don't know too much about the "hopping" part either, because dinosaurs have been extinct for millions of years and we can never know for sure.

The sudden mass extinction of the non-avian dinosaurs, which occurred around 65 million years ago, is one of the most intriguing mysteries in paleontology. Many other groups of animals also became extinct at this time, including ammonites (nautilus-like mollusks), mosasaurs, plesiosaurs, pterosaurs, herbivorous turtles and crocodiles, most birds, and many groups of mammals.[32] The nature of the event that caused this mass extinction has been extensively studied since the 1970s. At present, several related theories are broadly supported by paleontologists.\n\nAsteroid collision\nMultiple collisions—the Oort cloud\nEnvironment changes

Whether or not T-Rex evolved into a bird is still being debated among scientists.\n\nEarlier this year it was announced that the "Father" of T-Rex had been found. Some scientist think this particular animal might have had feathers.\n\nHowever, it is generally believed that T-Rex had a respiratory system similar to modern birds, e.g. the sparrow. \n\nOn July 13, 2005 CNN published an online article on this subject: "Study: T.rex had bird-like respiratory system." \n\nHope this helps.
