It's not every day that you can meet up with a Megatherium
– one of South America's giant prehistoric ground sloths – on a street in
England, or anywhere else, for that matter, unless that street just so happens
to be Downing Street (no, not that one!), in the English university city of
Cambridge. For if it is, you can walk along it and gaze up at a Megatherium
as often and for as long as you want to. And not just at a Megatherium
either, as it will always be in the company of another palaeontological
stalwart, the famous ornithischian dinosaur known as Iguanodon. Bemused?
Allow me to explain.

The Megatherium and Iguanodon in
question are a pair of large, ornamental carvings flanking (or supporting, to
use the correct heraldic term) the university's coat of arms present above the
archway of one of the entrances to the Sedgwick Museum of Earth Sciences. Also
referred to as the Sedgwick Memorial Museum, it is based in Downing Street, Cambridge, and constitutes the oldest of this university's
eight academic museums.

This museum is named in honour of one of England's most celebrated geologists, the Reverend Prof. Adam
Sedgwick (1785-1873), who spent his academic life working at the University of Cambridge, and it was built to honour him and to contain his very sizeable
collections of geological and palaeontological specimens, as well as those of
English naturalist Dr John Woodward (1665-1728). Woodward was a fellow
geologist who had bequeathed to the university half of his collection of over 9,000
specimens amassed by him over 35 years (the university subsequently purchased the
other half), together with funds to establish the Woodwardian Professorship of
Geology there (and to which Sedgwick was in due course appointed).

These collections were all held at that time in what
was then the university's Woodwardian Museum, established in 1728, but which would
require a much greater capacity if it were to accommodate further additions. Hence
the building of a bigger museum, honouring Sedgwick, was duly proposed. After
several delays and false starts, the Sedgwick Museum's construction was finally
approved on 16 February 1899, under Prof. Thomas Graham Jackson as architect,
and was officially opened on 1 March 1904. Built at what was back then a
notably expensive cost of £40,000, it now contains the collections of Woodward,
Sedgwick, and countless other specimens too, currently totalling around 2
million rocks, minerals, and fossils.

One of the Sedgwick Museum's most celebrated specimens on display is the very imposing replica cast
of a complete skeleton of an Iguanodon bernissartensis, which was donated
to the University of Cambridge by Brussels-based palaeontologist Louis Dollo during the late 1880s
via King Leopold II of Belgium. At least 38 complete or near-complete Iguanodon
skeletons had been recovered from a coal mine at the Belgian town of Bernissart in 1878. Nine of them were subsequently assembled
as upright-standing mount specimens for display at the Royal Belgian Institute
of Natural Sciences in Brussels (a total of 30 Iguanodon specimens can
be seen in its Museum of Natural Sciences today), and it was from one of these
that the cast prominently on display at the Sedgwick Museum was taken. This
famous exhibit in turn explains the choice of an Iguanodon as one of the
two supporters carved above its Iguanodon/Megatherium archway.

True, the skeleton cast's upright, rearing stance is
now deemed to be incorrect (modern-day palaeontological belief holds that Iguanodon
adopted a more horizontal stance), but back then this was how science assumed that
this very sizeable dinosaur form stood in life, and explains why the archway's Iguanodon
carving is also depicted in upright stance (note too the dragonesque series of
dorsal triangular spines running down the carving's back – another now-rejected
morphological feature). Moreover, being directly inspired by this cast, the
museum's logo has always been an upright bipedal Iguanodon as well (it
would be too costly and troublesome to change it now, especially as the logo is
so well known).

As for the Megatherium: the Sedgwick Museum's collection includes a partial Megatherium skeleton (and also
a historic cast of it) that formed part of Sedgwick's original (1840)
Woodwardian Museum collection. Moreover, the Sedgwick Museum is closely associated with Charles Darwin, as it houses a number of
his scientifically-priceless specimens, and he famously discovered a Megatherium
skeleton during his South American voyages, so the choice of this mega-mammal
as the second supporter carved over the archway serves as a very apposite
visual representation of this museum's Darwin links. In 2009, it curated a major public exhibition
entitled Darwin the Geologist, to coincide with the Darwin bicentenary celebrations (Darwin was born in 1809).
This exhibition focused upon his early geological research, and it displayed
many of the specimens collected during his famous Beagle voyage.

Incidentally, the Iguanodon and Megatherium
are not the only prehistoric beasts depicted externally at the Sedgwick Museum. So too is the woolly mammoth Mammuthus primigenius, courtesy
of the following detailed relief – present just to the left of the museum
entrance whose archway bears the above-noted dinosaur and ground sloth carvings:

The Sedgwick Museum is open six days a week (closed on Sundays and some Bank Holidays),
has free entry, and contains countless fascinating geological and palaeontological
specimens on public display – click here to visit its
official website for full details. So why not wander down Downing Street, introduce yourself to the Iguanodon and
meet up with the Megatherium as they stand tall in stately support, before
entering the wonderful world of our planet's distant past as encapsulated
within this celebrated museum's spectacular array of exhibits and displays?

And if anyone can tell me the name of the sculptor
who produced the Iguanodon and Megatherium carvings (and
presumably the woolly mammoth relief too), I'd be extremely grateful, because I
have so far been unable to discover this – many thanks indeed!
