Some dinosaurs ate lizards, turtles, eggs, or early mammals and some hunted other dinosaurs or scavenged lifeless animals. Most, however, ate vegetation (but not grass, which hadn't evolve yet). Rocks that contain dinosaur bones also contain remnant pollen and spores that indicate hundreds to thousands of types of plants existed during the Mesozoic Era. Many of these plants had ripe leaves, including evergreen conifers (pine trees, redwoods, and their relatives), ferns, mosses, horsetail rushes, cycads, ginkos, and in the latter part of the dinosaur age blossoming (fruiting) plants. Although the precise time of origin for flowering plants is still unsure, the last of the dinosaurs certainly had fruit available to eat.

Let us start with the present record holder, the dinosaur formally described as the biggest known to science, at least for the time being. This honour goes to the South American Sauropod Argentinosaurus (Argentinosaurus huinculensis). This massive dinosaur was officially named and described in 1993. It is only known from a few incomplete bones, including a femur and some vertebrae, (backbones). The vestiges were found in Argentina, hence the name. The tallest vertebrae are over 1.2 metres high. In comparisons with better known Sauropods size estimates for this dinosaur have been complete. These estimates vary significantly, with some scientists suggesting that this dinosaur may have been over forty-five metres long and weighing something close to seventy tones. Other more traditional estimates as to the size of this animal have been made, with a length of a little over one hundred feet being agreed upon by some palaeontologists. It is surely, true that this Cretaceous giant was an enormous animal, but until more fossils are found the true size of this dinosaur can only be predictable. A number of museums have capitalised on the reputation of the largest dinosaurs and equipped mounted replicas of this particular giant. The largest of these museum exhibits measures over thirty-five metres in length, but here again, without more fossil proof this display is largely speculative.

Is this the 'missing link' between dinosaurs and birds? Vestige egg discovered in Spain shows 'common forebear
The 'missing link' which proves the relationship among dinosaurs and birds may have been found.
It is a widely-held view that dinosaurs and birds share the same heritage, and an egg exposed in the Montsec area of Lleida, near Catalonia in Eastern Spain, shares individuality of both species.
The dinosaur egg, dating back 70 to 83 million years, has an oval shape, similar in exterior to a chicken egg, and an 'air bag' inside which birds today use to respire in the last stages of its growth.
The new type of dinosaur egg has been given the technical name of Sankofa pyrenaica and is the only dinosaur egg in the world to have an oval shape, alike to that of chicken eggs.
Nieves López Martínez, palaeontologist of the Complutense University of Madrid, was working on investigate of dinosaur eggs before her death in December 2010.
Together with Enric Vicens, palaeontologist of the Universitat Autònoma de Barcelona, the two scientists conducted a thorough analysis of their detection, now published in the journal Palaeontology.
The South Pyrenean area is rich in dinosaur egg sites, most of which communicate to sauropod eggs from the upper Cretaceous, dating back more than 70 million years ago.
During that period, the area was a coastal area full of beaches and deltas which won land from the sea through residue buildup.
Sand and mud from that period gave way, millions of years later, to the stonework and marl where dinosaur leftovers now can be found. On the seashore ridges and flat coastal lands is where a large group of dinosaurs laid their eggs.
The sites anywhere the discoveries were made correspond to the upper Cretaceous, between the Campanian and Maastrichtian periods, some 70 to 83 million years ago.
The fossils found belong to small eggs measuring some 7 centimeters tall and 4 cm wide, while the eggshell was on standard 0.27mm thick.
Most of the eggs found were broken in small wreckage, but scientists also discovered more or less complete eggs, which can be easily deliberate in sections.
The eggs found at the sites all belong to the same species. The main difference when compare to other eggs from the same period is their irregular shape, similar to that of chicken eggs.

Well this is going to be one of those harsh questions to answer, but I'm going to give it my best explosion. Was Jesus actually here before the dinosaurs? Let's see if we can solve this anonymity and get down to the bottom of creation.
The first opportunity that we can take, is to find out when Jesus was actually born? Our best guess for Jesus' birth, would be somewhere between 0 and 5 C.E. without knowing the precise day or month that he was truly born. With that in brain, there haven't been any dinosaurs that I know of, after this time period.
So obviously Jesus wasn't here before the dinosaurs, unless Jesus and God are the same entity and that both of them were created approximately the same time period. Now is when things start to get a little mystifying. If Jesus was created about the same time that God was shaped, Jesus would have been here before the dinosaurs.
Maybe, or maybe not! Could the dinosaurs have actually been here before God and Jesus were born? This is the kind of stuff that goes during my mind on a daily basis and there is nobody that can really clear the fog out of the room, by answering these questions whether lucid answer.
Here's the one obsession that I do know for a fact, I don't really know if Jesus was here before the dinosaurs or after, because I really don't have any evidence that Jesus was ever born or lived. At the same time, I truly don't know for a fact, that dinosaurs existed.
By reading books like the Bible and history books, I can tell you that scientists have found bone structures that could easily hold theories that dinosaurs roamed the earth, but I have very little evidence to sustain the claims made in the Bible about the life of Jesus of Nazareth.

Chechnya's huge Dinosaur Egg Discovery - Doubts Raised
Previous this week we were sent some pictures taken by a team of scientists who were investigative what was thought by a number of observers to be the fossilized remains of dinosaur eggs. There have been a substantial number of stories about this discovery in newspapers, journals and in both on-line and off-line media. Edifice workers responsibility the building of a new road were blasting their way through a hillside near the Chechen border with Georgia when the detection of more than forty, strange, spherical objects entrenched in the hillside was made. The strange objects, ranging in size from a few centimeters across to a whopping 1.02 meters were described as being dinosaur eggs and their discovery led to a "scramble" among scientists to learn more.
Stimulating Find in Chechnya
Dinosaur fossils are practically unknown from this part of south-eastern Europe. To find a whole array of dinosaur eggs, some of them three times the size of any other eggs recognized from the fossil record is truly extraordinary.
The Chechnya region has suffered in the past twenty years or so as separatist movements fought with Russia in a bid to form a sovereign state. The war-torn region has had millions of pounds (GBP equivalent) of state aid poured into it in a bid to improve the living circumstances for the local population, the road building project was one such regional growth measure, however, the planners did not "eggspect" to have a dinosaur egg pursue on their hands.

The fossilized remains of a fossil brooding in its nest have emerged from the red sandstones of the gobi wasteland in mongolia, providing new evidence for a far longer-lived and flexible species than previously thought.
Called mpc-d 107/15, the new specimen is an oviraptor, which is the only dinosaur ever found in the act of threatening. More specifically, it belongs to the class known as nemegtomaia barsboldi, a crested ostrich-like theropod that lived in late cretaceous mongolia.
A 70-million-year-old nest of the dinosaur protoceratops andrewsi has been found with proof that 15 juveniles were once indoors it, according to a paper in the latestjournal of paleontology.
While huge numbers of eggs have been connected with other dinosaurs, such as the meat-eating oviraptor or sure duck-billed hadrosaurs, judgment multiple juveniles in the same dino nest is fairly rare.

Researchers in Spain and Norway reported in the periodical Nature they had found tree-like growth rings on the bones of mammals, a characteristic that until now was thought to be limited to cold-blooded creatures and dinosaurs.
They also found proof that dinosaurs probably had a high metabolic rate to allow fast growth another pointer of warm-bloodedness.
"Our results strongly propose that dinosaurs were hot-blooded," lead author Meike Koehler of Spain's Institut Catala de Paleontologia told AFP.
If so, the findings should punctual a rethink about reptiles, she said.
Modern-day reptiles are cold-blooded, meaning they cannot control their body temperatures through their own metabolic system relying instead on outside means such as basking in the sun.
While the dinosaurs may have been hot-blooded, their other characteristics kept them directly in the reptile camp, said Koehler.
Paleontologists have long noted the ring-like markings on the bones of cold-blooded creatures and dinosaurs, and taken them to designate pauses in growth, perhaps due to cold periods or lack of food.
The bones of hot-blooded animals such as birds and mammals had never been correctly assessed to see if they, too, display the lines.
Koehler and her team found the rings in all 41 hot-blooded animal species they studied, counting antelopes, deer and giraffes.
The finding "eliminates the strongest quarrel that does survive for cold-bloodedness" in dinosaurs, she said.
The team's analysis of fillet tissue also showed that the fast enlargement rate of mammals is related to a high metabolism, which in turn is characteristic of hot-bloodedness.
"If you compare this hankie with dinosaur tissue you will see that they are equal," said Koehler.
"So this means that dinosaurs not only grew very fast but this increase was sustained by a very high metabolic rate, representative hot-bloodedness."
A comment by University of California palaeontologist Kevin Padian that was available with the paper said the study was the latest to chip away at the long-held theory that dinosaurs were cold-blooded.
"It seems that these were anything but characteristic reptiles, and Koehler and colleagues' findings remove another false association from this picture."
