Plesiosaurs “Flew” through Water Like Penguins

By | December 19th, 2015|General Teaching|Comments Off on Plesiosaurs “Flew” through Water Like Penguins

How did Plesiosaurs Swim?

Plesiosaurs are marine reptiles, not dinosaurs and they roamed the seas for much of the Mesozoic.  Fossils of these long-necked, round bodied reptiles have been found in many parts of the world.  The geological record of plesiosaur fossils spans some 135 million years.  However, palaeontologists have debated, almost since the time of Mary Anning, how these carnivorous animals actually moved through water.  It turns out that these animals, some of which were as long as a school bus, actually “flew” through the water, swimming with their front paddles, in virtually the same way that penguins do today.

A Study of the Locomotion of Plesiosaurs

Studying How Plesiosaurs Moved through Water

Plesiosaur "flight" study.

The most effective swimming motion for the plesiosaur is flapping the two front flippers in an underwater flight motion

With the help and support of plesiosaur fossil expert Dr Adam Smith (Nottingham Natural History Museum, Wollaton Hall), a team of researchers from the School of Interactive Computing  at the Georgia Institute of Technology, Atlanta, Georgia, United States) recreated the swimming motions of a three-metre-long, Early Jurassic plesiosaur, whose fossils come from Germany, (Meyerasaurus victor).

Using a Computer Model

A three-dimensional computer model of the marine reptile was created and then various swimming modes were tested.  The most efficient locomotion was achieved when just the front flippers were used.  It seems that the rear limbs did little in the way of helping to create forward thrust and momentum.  Instead, they were probably used for steering and keeping stable in the water column.

Commenting on the research, Dr Smith stated:

“Plesiosaur swimming has remained a mystery for almost 200 years, so it was exciting to see the plesiosaur come alive on the computer screen.  Our results show that the front limbs provide the powerhouse for plesiosaur propulsion while the hind limbs are more passive”.

Everything Dinosaur stocks an extensive range of marine reptiles models. There are replicas of plesiosaurs, pliosaurs and ichthyosaurs available, plus a variety of other sea monsters and ocean-going prehistoric creatures.

Saturday and Still Working

Preparing and Packing Orders for Everything Dinosaur Customers

It has been dubbed “stressful Saturday” the last Saturday before Christmas Day.  Lots of shoppers racing around in a desperate rush to get the presents bought.  Team members at Everything Dinosaur do understand that at this time of year Christmas shopping can be a stressful experience.  In the mail order world for example, not only is there the stress in looking for the ideal gift on line but in addition, there is the worry as to whether or not the present is going to be packed and despatched so that it can be delivered in time for the big day.

We Don’t Want Present Buying to be a Nasty Experience!

Plans already in place to help out with Christmas orders.

Saturday and Still Working

For several weeks now Everything Dinosaur has been implementing a number of seasonal policies to help our customers at this time of year.  Naturally, we still email customers in person to let them know that their order has been received, but in addition, the extra shifts put in has meant that we have kept on top of the orders and that parcels and packages have been despatched promptly.  All orders placed prior to 3.30pm on Friday, for example, were despatched late that afternoon (around 4.30pm), these parcels are already on their way.

Today, Saturday, we have team members in the office manning the phones, taking calls from customers looking for reassurance about delivery dates, getting telephone orders sorted and so on.  All the orders received up to 10.15am on our website were sent out with the Saturday morning 11am collection.  These parcels too, are in the mail network by now.

Last Recommended Posting Dates

We always advise people to post early, this is the best policy in our view, but here are the last recommended posting dates from Royal Mail and our main courier service company (Interlink):

  • Today, Saturday 19th December for second class parcels
  • Monday 21st December for first class parcels
  • Wednesday 23rd December for Royal Mail Special Delivery*

With couriers, Everything Dinosaur subsidises carrier charges and the last day for the majority of UK deliveries using courier despatch is Wednesday 23rd December (orders placed before 12 noon) for delivery next day, in time for Christmas, but please note, not all parts of the UK are covered by a next day delivery service and at this time of year, courier networks experience very high levels of demand and not all next day deliveries can be guaranteed.  We advise that customers email Everything Dinosaur so that we can provide individual assistance or alternatively, the Interlink website provides information on their services.
