Name means: “Wealden lizard”
Length: 10 ft (3 m)
Time: Early Cretaceous, 144 – 113 mya
Place: England, Romania, possibly Niger
This poorly-known small dinosaur is believed to have been a hypsilophodontid.
If so, Valdosaurus would have been a nimble, large-eyed plant-eater
with long running legs and deft fingers. Valdosaurus was named in 1977.
Taxon: Theropoda Maniraptora Dromaeosauridae
Name means: “Var plunderer”
Length: 6.5 – 10 ft (2 – 3 m)
Time: Late Cretaceous, c. 71 mya
This sickle-clawed predator, a relative of Deinonychus and Velociraptor,
was named after the Var River of southern France in 1998. A clever,
agile hunter like the other maniraptors, Variraptor was probably well-equipped
to take down larger prey.
Name means: “Isle of Wight lizard”
This dinosaur is now known to be IGUANODON.
Taxon: Theropoda Dromaeosauridae
Name means: “swift robber”
Length: 6.5 ft (2 m)
Time: Late Cretaceous, 85 – 80 mya
Place: Mongolia, China, possibly Russia
This “sickle-clawed” dromaeosaurid was made famous in the
movie “Jurassic Park.” Unlike its giant silver screen counterpart,
the real Velociraptor was a small, lightly-built predator with a long,
low snout and large eyes. Like all dromaeosaurids, Velociraptor had
a relatively large brain, long, flexible arms, dexterous fingers tipped
with sharp grasping talons, and a tail stiffened by rigid, rod-like
tendons, providing balance for leaping and delivering deadly slashing
kicks to its prey. These kicks were made all the more devastating by
the large, extendable talon on the second toe of each foot. The famed
“Fighting Dinosaurs” specimen of Mongolia indicates that
Velociraptor hunted the small ceratopsian Protoceratops, although that
particular Velociraptor did not survive the deadly battle. This genus
was named in 1924.
Taxon: Theropoda Velocisauridae
Name means: “swift lizard”
Length: 3 – 5 ft (1 – 1.5 m)
Time: Late Cretaceous, 73 – 65 mya
The leg and foot bones of this small, lightly-built theropod suggest
that it was a very fast runner, well-equipped for chasing down small
prey such as Cretaceous mammals, lizards and insects. Velocisaurus was
named in 1991.
Taxon: Sauropoda ?Brachiosauridae
Name means: “for Volkheimer”
Length: 29.5 ft (9 m)
Time: Middle Jurassic, 169 – 163 mya
Thus primitive long-necked sauropod was named for Argentine geologist
and paleontologist Wolfgang Volkheimer in 1979. Volkheimeria is generally
considered to be a member of the high-necked, slope-backed brachiosaurids.
Taxon: Sauropoda Vulcanodontidae
Name means: “volcano tooth”
Length: 21 ft (6.5 m)
Time: Early Jurassic, 208 – 201 mya
Known from a partial skeleton but missing a skull to study, the long-necked
plant-eater Vulcanodon was originally classified as an advanced prosauropod.
It is now generally considered by paleontologists to have been one of
the earliest, most primitive and prosauropod-like members of the four-legged
sauropod dinosaurs. The teeth for which Vulcanodon was named in 1972
were discovered in volcanic rock and actually came from a predatory
dinosaur which may have been scavenging the plant-eater’s remains.
