Ichthyosaurs were large marine reptiles that lived through most of the
Mesozoic Era.
They seem to have evolved from a group of terrestrial reptiles
(a group which is still to be identified) during the early
Triassic period,
about 245 million years ago, initially looking rather like lizards with fins.
Ichthyosaurs continued to evolve during the
Triassic period,
and both dolphin-like and somewhat serpent-like forms existed, the latter sometimes
growing to huge sizes, as much as 50 feet (15 meters) in length.
By the early Jurassic period,
Ichthyosaurs had reached their peak of diversity, and a long slow decline in diversity
continued through the
Jurassic and into the
Cretaceous period.
The last Icthyosaurs finally became extinct during the middle to late
Cretaceous,
perhaps about 90 million years ago.
In outward physical form, Ichthyosaurs tend to resemble whales, dolphins or sharks. This
is a result of convergent evolution - sharks, cetaceans (whales, dolphins and porpoises),
and ichthyosaurs all evolved similar body shapes, because it is a good hydrodynamic
solution for swimming.
Fossilized ichthyosaur:
One difference between Ichthyosaurs and many other marine predators, is
that it is believed that Ichthyosaurs probably hunted by sight (rather
than for example echo-location). Part of the evidence for this is that
Ichthyosaurs generally had comparatively large eyes - one particular
genus of Ichthyosaur, namely Temnodontosaurus which lived in
Jurassic
Europe
and was about 30 feet (12 meters) long, had the largest eyes of any
known vertebrate - its eyes were 10 inches (26 centimeters) in diameter.
Another noteworthy fact about Ichthyosaurs is that at least some species,
perhaps even all species, seem to have given birth to live young. The
evidence for this is that
fossils have been found
of Ichthyosaurs containing fossils of babies within the abdomen. It has
been suggested that perhaps these babies were stomach contents and therefore
evidence of cannibalism, however it seems more likely that
these fossils show
a pregnant Ichthyosaur that died just before (or perhaps even during)
giving birth.
Fossil fragments of Ichthyosaurs have been known since at least 1699, however the
the first complete fossil specimen was found by
Mary Anning in 1811 in Lyme Regis,
England
(Mary Anning
subsequently discovered three species of Ichthyosaur).
A large number of other fossils were also found by a
1905
expedition to central
Nevada,
including a 55 foot (17 meter) Shonisaurus (a very large, late
Triassic
Ichthyosaur), which since
1977,
has been designated as
Nevada's
State Fossil.
Ichthyosaurs were marine reptiles that lived between 245 and 90 million years ago

Kindle Edition (50 pages)
 | | Product Description:
On the 21st of May 1799 a baby girl was born to Richard and Mary Anning, Lyme Regis, Dorset. The daughter was christened Mary and she grew up to become one of the most famous fossil hunters of her age. She collected and studied fossils found in the surrounding cliffs of the Jurassic coast. Mary’s contribution had a major impact when scientific enquiry was leading to a change in the way people thought about the evolution of life and our planet - a story that would culminate with Charles Darwin's; ‘On the Origin of Species', published in 1859.
This is a factual history of England’s most famous fossil hunter Mary Anning and her major finds, which included ichthyosaurs, plesiosaurs and a pterodactyl. It also includes notes on other major pioneering palaeontologists of her time, including William Buckland, Henry de la Beche and William Conybeare, who were her friends and mentors.
The author Nigel J. Clarke, a life-long resident of Lyme Regis, has also written “Lyme Bay Fossils”, the best selling guide to the fossils of the Jurassic coast. In the summer months he conducts regular guided fossil hunts along the same cliffs and beaches as Mary Anning once frequented.

Neptune's Ark illuminates the dramatic saga of evolution spanning 500 million years of marine life along the magnificent Pacific coast of western North America. In an engaging narrative that artfully blends elements of science, history, folklore, and personal observation, renowned naturalist David Rains Wallace reveals a marvelous diversity of creatures, not only modern ones, but those from the far prehistoric past. Mysterious forms have abounded—from giant sea cows, oyster bears, and flightless toothed birds to the orcas, elephant seals, and sea otters of modern times. Wallace tells a story about evolution as well as a tale of the storms, scurvy, and shipwrecks that plagued the coast's explorers, naturalists, and scientists, many of whom led turbulent or tragic lives, with themes reflected in the wonder and danger of the coast itself. Neptune's Ark is full of vivid characters—from explorers like Sir Francis Drake and Captain James Cook, to pioneer naturalists including Georg Steller and Charles Scammon, to early paleontologists Othniel Marsh and Edward Cope, and to recent scientists and ecological visionaries. |

Criticism about the neo-Victorian novel ― a genre of historical fiction that re-imagines aspects of the Victorian world from present-day perspectives ― has expanded rapidly in the last fifteen years but given little attention to the engagement between science and religion. Of great interest to Victorians, this subject often appears in neo-Victorian novels including those by such well-known authors as John Fowles, A. S. Byatt, Graham Swift, and Mathew Kneale. This book discusses novels in which nineteenth-century science, including geology, paleontology, and evolutionary theory, interacts with religion through accommodations, conflicts, and crises of faith. In general, these texts abandon conventional religion but retain the ethical connectedness and celebration of life associated with spirituality at its best. Registering the growth of nineteenth-century secularism and drawing on aspects of the romantic tradition and ecological thinking, they honor the natural world without imagining that it exists for humans or functions in reference to human values. In particular, they enact a form of wonderment: the capacity of the mind to make sense of, creatively adapt, and enjoy the world out of which it has evolved ― in short, to endow it with meaning. Protagonists who come to experience reality in this expansive way release themselves from self-anxiety and alienation. In this book, Glendening shows how, by intermixing past and present, fact and fiction, neo-Victorian narratives, with a few instructive exceptions, manifest this pattern. |
