Probably no creatures that have lived upon this Earth have excited the imagination more than the Dinosauria. For some 150 million years they dominated over the medium to large to gigantic terrestrial ecological niche, evolving into a wide range of forms and populating every continent. Our infatuation is perhaps because they often had such bizarre forms, perhaps because they sometimes grew to such huge size, perhaps because after ruling the Earth for so long they suddenly vanished, seemingly without a trace; all things add to the appeal of the Dinosauria in the popular - and scientific! - imagination.

While dinosaurs have gripped people's imaginations like no other creature of the past, and as wonderful as the dinosaurs were, they should be considered in the context of many other fascinating and wonderful creatures, both extinct and extant. True, many dinosaurs did have rather strange forms, but were they any stranger in appearance than, say, a giraffe or an elephant? True, many dinosaurs grew to be quite large and even enormous, but no dinosaur ever rivalled the size of a smaller . It would, in fact, be physiologically impossible for a land animal of more than 100 tonnes to exist, since structural support would require it's legs to be so massive they would touch, leaving no space for the body between! So much for Godzilla and the dinosaurs of One Million Years B.C. (a cult film better known for a much smaller, but equally impressive, 60 kg and 180 cm Rachel Welch in a fur bikini) - such creatures belong to the realm of Hollywood fantasy. The majority of dinosaurs were actually medium-sized creatures, equivalent to modern, medium to large mammals in size. Finally, as for dying out without a trace, this is also incorrect. One lineage of small insectivorous and carnivorous dinosaurs did survive the great terminal extinction and are still with us today -- they are called .

Eoentantiornis buhleri, a Cretaceous from Liaoning Province of China

Some ecological niches the dinosaurs didn't invade. They never established themselves in the small terrestrial vertebrate niche (this was already taken over by mammals and lizards), nor (contrary to popular belief) did any of them ever adopt a marine or aquatic mode of life. They did, however, take to the air with style; and so successfully that their descendents are still the most numerous and diverse of the (land-living vertebrates) even today. While their is no evidence in the fossil record that the pre-avian dinosaurs could fly, there were many flying, non-avian reptiles that lived during the time of the dinosaurs. Notably, the including Pteranodon, Pterodactylus, Dimorphodon, and numerous others, hunted and eluded hunters via flight.(MAK 010930)

Traditionally, the dinosaurs were divided into two , depending on the structure of the hip bones. Those that had a reptilian-like pelvic bone were put in the Order Saurischia or "lizard-hips"; while the ones with a bird-like pelvic bone made up the Order Ornithischia or "bird-hips". (Paradoxically, it was from "lizard-hipped" and not the "bird-hipped" forms that birds evolved). This classification is still adhered to in some (especially older) popular and academic books, but has pretty much been rejected in favour of the cladistic interpretation.

The earliest proto-dinosaurs[1] (basal ) were a group of small early dinosaur-like archosaurs, known only from a few scrappy Argentinian fossils of age. These are neither saurischian nor ornithischian. These creatures, previously considered ornithosuchid thecodonts, are not even formally considered dinosaurs (although they are dinosauromorphs, which means dinosaurs and a few related forms more closely related to dinosaurs then to pterosaurs.). They are the stem forms from among which which the dinosaurs evolved. It has also for some years been felt that they are closely related to the (flying reptiles). There is however a rival theory which derives the pterosaurs from "lizards," or perhaps even more distantly related stock.

See and for more.

The Saurischia or "lizard hipped" dinosaurs are those more closely related to than to Triceratops. Conventionally, they are divided in turn into two groups, one largely carnivorous, the other herbivorous. The first of these are the , the bipedal carnivorous dinosaurs, with their bird-like legs and necks. Theropoda means "beast-feet", a rather inappropriate name; "bird(-like) feet" would have been better. Included in this huge and diverse group are both small forms (including the birds themselves) and large predators such as and .

The other group of Saurischia, the , were herbivores. There are two main subgroups, the (the inappropriately named "lizard-feet"), and their ancestors or uncles, the ("before the sauropods"). Although the prosauropods were relatively small, the more advanced types, and all of the sauropods, were elephantine giants with tiny heads, very long necks and tails, massive bodies, and pillar-like legs. This group includes the famous "Brontosaurus" (or Apatosaurus) and its relatives. Like modern-day elephants, they relied on their great size as a defense against carnivores.

See for more.

The Ornithischia ("bird hipped" dinosaurs), or Predentata (so called beacuse they posses a unique extra predentary bone in front of the jaw, which served as a sort of beak) were a more diverse group of herbivores. Being much smaller than the sauropods, they survived because they evolved various other means to avoid becoming fast food for their meat-eating theropod contemporaries. The ornithopods, for example, depended on fleetness of foot and acute sight and hearing. The dinosaurs (Triceratops, etc) were the rhinoceroses of the dinosaur world, their formidable horns at least appear to be ample protection against even the largest and fiercest carnivores. There is a substantial body of opinion that these horns were more decorative than functional - although we have probably not heard the end of this issue. The and evolved armour plates, spikes, and tail-clubs as defensive and offensive weapons.

The Ornithischia - unlike saurischian dinosaurs, reptiles and birds - possessed mammal-like cheek muscles and cheek pouches to aid in chewing. In this respect they paralleled the mammalian form. Certainly, many Ornithischia filled ecological roles similar to those of the mammalian ungulates.

See for more.

So we see among the dinosaurs the tendency towards both an avimorphisation or bird-form-tendency in the Theropods, and a theromorphisation or mammal-form-tendency in the Ornithischia. The dinosaurs of the Mesozoic era in a sense presaged the birds and mammals of the Cenozoic era.

A word now about . Most palaeontologists and dino-enthusiasts today also consider the birds to be a subgroup of dinosaurs. Cladistically (phylogenetically) speaking this is correct: birds evolved from dinosaurs, so if dinosaurs are to retain their monophyletic status they must include birds. MAK010930. Revised ATW050609.

[1] The discussion here assumes a more or less conventional view of evolution. We are aware of unpublished work which might drastically alter this view. For both scientific and historical reasons, the data sets used to produce the present consensus tree of the archosaurs are weak. Some of those factors are discussed elsewhere. A complete restructuring of archosaur evolution, based on new data, is not at all out of the question.

The limiting factor is that muscles contract only about 30% of their length. Increasing muscle length therefore increases motion of the bone.

The tetrapod model of the pelvic girdle consists of a simple, tri-radiate structure. Pubis, ilium and ischium meet at Y-shaped junction. The acetabulum is located at the junction, and head of femur extends outward at 90° along its long axis. Protraction: Pubis extends antero-ventrally. Muscles insert on femur (pubofemoral) and protract (forward) it. Retraction: Tail (and/or ischium?) extends posteriorly and retract femur (caudofemoral). Abduction: Ilium extends posteriorly and muscles inserting on femur abduct it towards mid-line. Basic Tetrapod pelvis is plate-like. Extensions of pelvic bones are relatively small, and ilium articulates with only 1-2 vertebrae in sacrum. Muscles to pubis and ischium extend ventrally, countered to some extend by iliofemoral muscles.

The problem is that as the femur rotated downwards to become more vertical, the length of the muscle running from the pubis and ischium shortened relative to the length of the femur.

The solution common to all dinosaurs is an open acetabulum with bracing dorsally. Saurischians compounded on this with an extended pubis an ischium and rotated pubis antero-dorsally. Early ornithischians retroverted pubis, having it parallel to the ischium, and protracted the femur by attachment to anterior extension of ileum (see image). Later ornithischians secondarily developed an anterior projection of the pubis, as well as retaining the retroverted shaft.

NSAIDs include several widely used drugs, such as ibuprofen or naproxen. Contraindications As challenging as erectile dysfunction is on its own, it can also be a warning sign for more serious problems, such as heart disease. Men who experience even mild erectile dysfunction (ED) have about a 25 percent greater risk of heart disease, including heart attack and stroke, than their peers. This means that, for some men, erectile dysfunction is a stronger predictor of heart disease risk than family history, smoking, or high cholesterol levels. And the more severe your ED, the greater your risk of heart disease-related events. The researchers found that the overall prevalence of erectile dysfunction among U.S. men was 18.4 percent. Age was a strong risk factor -- men 70 and older accounted for 70 percent of those with erectile dysfunction. In contrast, just 5 percent of men with erectile problems were between the ages of 20 and 40.
