Supporting Literacy at Summer School

By | August 4th, 2015|General Teaching, Key Stage 1/2|Comments Off on Supporting Literacy at Summer School

Kingswood Primary Academy Learn About Dinosaurs

It may be August and the school holidays but there is no rest for the dedicated teaching team at Everything Dinosaur.  Today, Everything Dinosaur visited Kingswood Primary Academy (Northamptonshire), to support the summer school focusing on literacy with a dinosaur theme.  The children, the majority of which are at Key Stage Two, took part in  a number of exercises and activities with a dinosaur and fossil theme.

Everything Dinosaur

One of our dinosaur experts led a tactile fossil handling session exploring how fossils form and what they can teach us about life in the past.  In addition, we supplied an array of resources including fact sheets, drawing materials and lesson plans to help the teachers.  The children were challenged to design their own dinosaur and we saw some wonderful, creative prehistoric animals.

Dinosaurs Helping with Literacy

With the focus on literacy, we challenged the children to include lots of labels and information about their dinosaur creation.

In a third session over the day, we helped the children build a dinosaur timeline so that they could show which prehistoric animals lived during the Mesozoic Era.  Using pegs and string the children, helped by the enthusiastic teaching team at Kingswood Primary Academy produced a set of super dinosaur timelines featuring lots of different dinosaurs and prehistoric animals.

Prehistoric Animal Fact Sheets

Once again, we encouraged the children to include lots of facts and information on their dinosaur and prehistoric animal timelines. The summer school, which will run over the next two weeks, has certainly got off to a great start.

Commenting on Everything Dinosaur’s contribution Andy Bark, (class teacher for Year 5) stated:

“The activities engaged and motivated the children and it was a super day!  Thanks.”

The children at Kingswood Primary Academy enjoyed the start of their dinosaur themed summer school with a visit from a fossil expert from Everything Dinosaur to help kick-off proceedings.  We will be back next week to provide further support and assistance to the teaching team.  Next week, we are off on a fossil hunt!

Four-Legged Snake Fossil Slithers into Legal Dispute

Tetrapodophis amplectus Fossil Provokes Legal Action

Back on July 24th, Everything Dinosaur reported on the publication of a scientific paper that provided an insight into how snakes evolved from limbed ancestors.  The fossil of a snake-like creature with four tiny legs had been spotted on a tour of a German museum quite by chance.  It’s significance had not been realised until Dr David Martill (University of Portsmouth), spotted the beautifully preserved fossil whilst taking a party of his vertebrate palaeontology students on a visit to Germany to explore some of the country’s natural history museum fossil collections.

Tetrapodophis amplectus

The unique specimen is believed to have been excavated from the Crato Formation of north-eastern Brazil.  The animal has been named Tetrapodophis amplectus , the name means “four-legged” embracing snake”, as the limbs probably did not have much of a locomotive function but probably served as claspers in mating or helping to control and manipulate prey.

With the paper published, a legal dispute has arisen with the Brazilian authorities and an investigation has begun to try to understand more about the provenance of the fossil material.  Brazil made it illegal in 1942 to sell or export fossils without the express permission of the Government.  The snake fossil was part of a private collection on display at the famous Bürgermeister-Müller-Museum in Solnhofen.  This museum, based in southern Germany, has amongst its fossil collection, spectacular Late Jurassic fossil specimens preserved in fine-grained, lithographic limestone.

By chance, during Dr Martill’s visit, the museum was putting on an exhibition of Cretaceous fossils from similar strata, but this time from Brazil.  Both the slab and the counter slab are known, but their exact provenance remains a mystery.  That’s the problem, it may have been collected prior to the Brazilian legislation, or perhaps it was collected after 1942, nobody is really sure.

Brazilian Officials Investigating

The Brazilian officials are keen to investigate to try to determine whether the snake fossil was taken out of Brazil illegally.  If this is the case, then they may have grounds for repatriation.

Commenting on the situation Felipe Chaves, (Head of the Fossil Division of the Brazilian National Department of Mineral Production, based in Brasilia), stated:

“We will formalise the request for an investigation with the Brazilian Federal Police, in order to ascertain how this fossil specimen left Brazil.  We know some details that merit being investigated.”

The twist in the tale highlights a major problem in palaeontology.  How much responsibility can scientists take when it comes to upholding the legality of the fossil specimens that they study?

High Prices for Fossils

Unfortunately, fossils, especially those of vertebrates, can fetch high prices.  There is a black market of illegal fossil material and many collectors are prepared to pay large sums for exquisite specimens.  This encourages the illegal excavation and trading of such artefacts.  There are a number of countries that have established tough laws to try to prevent the smuggling of fossil material, but there is a lot of evidence to suggest that illegal selling is still widespread.

To read an article about the seizing of a dinosaur fossil skeleton (T. bataar) that was put up for sale at a New York auction: U.S. Authorities Seize Dinosaur Fossil at the Centre of Auction Row.

Dr Nicholas Longrich, a palaeontologist at the University of Bath and a co-author of the fossil study stated:

“Personally, I would have liked to see the fossil go back to Brazil, but it wasn’t my fossil and so it wasn’t my choice.  We did discuss at length whether the specimen should be returned, given that we were uncertain about when it left, but the counterargument was that there was no evidence to suggest that any laws had been broken.”

After Paper Published Officials Became Aware of the Specimen

It was only when the scientific paper describing the snake fossil was published in the academic journal “Science”, that Brazilian Government officials became aware of the fossil’s existence. Felipe Chaves suggests that the research team should have informed the relevant authorities when they considered that this specimen most probably came from Brazil.  However, Dr Martill, the lead author of the Tetrapodophis scientific paper sees no need to do this.

He stated:

“There are hundreds, if not thousands of Brazilian fossils [in museum collections] all over the world.  It is a bit distracting if scientists have to mess about with the legality of fossils before they study them.  I see thousands of fossils every year from all over the planet.  I am not going to write to the governments of all those countries just to check each and every fossil.”

Looking at the Wider Point of View

Protectionist laws are in place in a number of countries, most notably China, where significant steps have been taken to try to reduce the smuggling of fossil material out of the country.  Such restrictions can hamper the collection and study of fossil specimens, but at the same time there is a need to protect a country’s heritage and to crack down on criminal activities.

Fossils from private collections often cause the greatest concern.  It can prove very difficult to establish how or when a fossil specimen was acquired.  However, should researchers publish data on fossils that may have been obtained illegally.

A number of academic journals produce guidelines to help clarify the situation, at least in so far as publishing a scientific paper.  For example, the academic journal “Cretaceous Research”, provides assistance to authors by noting in its author guidelines that papers on fossils of uncertain origin will not be accepted for publication, even if they are part of a museum’s collection.  The specimens must have unambiguous collection or ownership data associated with them.

Trying to Control the Exportation of Fossils

Given the wealth of vertebrate fossil material from the Crato and Santana Formations of Brazil in museums, it is doubtful whether the Brazilian investigation will make much progress.

A spokesperson from Everything Dinosaur explained:

“We can see both sides of the argument. Firstly, there is the desire to have controls on the exportation of fossil material and other artefacts from a country.  Retaining fossils in their country of origin can do much to encourage science education and research in that part of the world.  However, it is important to allow the continuation of research into fossils housed in various collections around the world even if their provenance can be described as a bit “murky”.  The important thing is to deter illegal collecting whilst at the same time encouraging a more open attitude towards scientific study.”

The spokesperson went onto add:

“Owners of private collections may be tempted to hide their collections away, thus denying scientists the chance to access them and to conduct research.”
