The dinosaur of the day: Ichthyovenator
- Spinosaurid that lived within the Early Cretaceous in what’s now Laos (Savannakhet Basin, “Grès supérieurs” Formation)
- Holotype estimated to be 28 to 34 ft (8.5 to 10.5 m) lengthy and weigh 2.4 tonnes
- Had straight, conical enamel (not serrated)
- Had a diminished pelvic girdle
- Neck much like Sigilmassaurus (Spinosaurus)
- Had tall neural spines on its again, that made a sail
- Had a sail on its again and hips
- Sail had a wavy (sinusoidal) form, curved downwards break up into two separate sails
- Seems to be type of like a bit of the sail is lacking
- Sail might have been for show or species recognition, or thermoregulation or for storing power
- Most likely semiaquatic
- Tail spines have been tall, might have helped it swim
- Might have used its tail to assist propel it by water
- Paleoart appears similar to Spinosaurus, particularly the tail, although the sail on the again is just not as tall
- Fossils present in 2010, discovered a partial skeleton (no cranium, no limbs)
- As a result of it’s a spinosaur, in all probability had an elongated snout and ate fish
- As a spinosaur, seemingly had sturdy arms and enormous thumb claws
- Described in 2012 by Ronan Allain and others
- Kind and solely species: Ichthyovenator laosensis
- Genus title means “fish hunter”
- Species title refers to Laos
- Extra fossils present in 2014, together with enamel, vertebrae, and a pubic bone
- Reported to be the primary particular spinosaur from Asia, however Siamosaurus had been named in 1986 (recognized principally from tooth fossils, there could also be two partial skeletons however it’s not but sure if they’re Siamosaurus)
- Initially regarded as a part of the subfamily Baryonychinae however now regarded as a primitive Spinosaurinae (due to non-serrated enamel and its vertebrae being much like Sigilmassasaurus)
- Different animals that lived across the identical time and place included sauropods corresponding to Tangvayosaurus, ornithopods, bivalves (mollusks), fish, and turtles
Enjoyable Truth:
The primary reconstruction of a fossilized animal may be a dragon statue in Austria—The Klagenfurt Lindwurm. It predates the Crystal Palace Dinosaurs by virtually 300 years.
