Swept to their deaths in South Ayrshire

The area around Girvan is well known as trilobite hunters’ paradise. Collectors and scientists have been visiting Girvan for over a century. An early collector, Mrs Elizabeth Gray (1831-1924), would picnic with her family on Sunday after church and collect fossils only from south facing sides of hills (the sunny side).

George Rae spent a lot of time collecting from one particular 447 million year old (Ordovician) rock exposure near Girvan called the Lady Burn Starfish Beds. The rocks revealed the remains of animals caught up in submarine slides that had dragged them into the murky depths of an ocean and entombed them in sand and sediment. As a result many of the fossils are complete and particularly well preserved.

He has researched in great detail the animals he has uncovered and has grouped them ecologically. A record of the exact position of each fossil, both vertically and horizontally within the exposed sedimentary rocks, was logged. All this information helps us to understand better the ecological interactions of life in the ancient Iapetus Ocean.


Stygina, trilobite, (Environment: Outer Shelf)

Length: 3 cm

Stenopareia, trilobite, (Environment: Outer Shelf)

Length: 8.5 cm

Paraproetus, trilobite, (Environment: Outer Shelf)

Length: 2 cm



George was first drawn to these rocks because of his interest in trilobites. His endeavours have resulted in the discovery of animals new to Science. Some of these are still to be described as, sadly, George died before he was able to complete his work. Many of the specimens in his collection are of such great beauty, or so well prepared, that there is nothing in the older collections that can compare.

Calymene, trilobite, (Environment: Shelf Edge to Slope)

Length: 3 cm

Cybeloides, trilobite, (Environment: Shelf Edge to Slope)

Length: 2 cm

Cybeloides (Length: 3.5 cm) and Tretaspis (X2) (width: 1 cm), trilobites, (Environment: Shelf Edge to Slope)




Hadromeros, trilobite, (Environment: Slope and deeper water)


Length (head): 10cm





Length (tail): 7cm


Calymene, trilobite, (Environment: Slope and deeper water)

Length: 6 cm


Paraharpes, trilobite, (Environment: Slope and deeper water)

Length: 4 cm


Tretaspis, trilobite, (Environment: Slope and deeper water)

Length: 3.5 cm (including spines)

Lonchodomas, trilobite, (Environment: Slope and deeper water)

Length: 6 cm (including spines)

Lonchodomas, trilobite (ready for preparation), (Environment: Slope and deeper water)

Length: approx.
7 cm (including spines)



Many of the specimens from the Lady Burn Starfish Beds are professionally prepared. George would carefully collect all parts of the fossil, glue them together again and mark out where the fossil was before sending it off for preparation.

Nankinolithus, trilobite, (Environment: Deeper water)

Length: 4 cm
