Scale
Wyoming, USA, 150 million years ago…
Waking from a fitful sleep, Hesper realised that the sun was peeking through the fronds of the cycad leaves above her. She was aware of a persistent drip-drip-drip close to her head, and as much as she had tried to make a bed of the ground ferns, she could still feel the damp earth beneath her claws and belly feathers. Warily, she raised her head, and confirmed the good news: it had stopped raining.
At first glance, any time-travelling human observer would have been forgiven for mistaking Hesper – or, as she would later be dubbed by palaeontologists, Hesperornithoides – for some kind of ground-dwelling bird. And to be fair, they would not be far wrong. She had a short head, a long stiff tail, a two-legged stance and a thick coat of russet feathers – the elongated feathers along her arms made them look like wings, though she could not, in fact, fly. Closer inspection, however, would reveal the mouth of sharp teeth in place of a beak, and the sickle claw on each foot, which betrayed her true nature as a non-avian dinosaur.
She was about two months old, and at less than two feet long, only half of her eventual adult size, assuming she made it that far. With a relatively short lifespan ahead of her, her mother and her siblings were a distant memory in her mind, though she had only parted ways with them a few days ago. At this stage in her life, her focus was on continuing to eat and grow; others of her kind were only competitors to be avoided, until she reached sexual maturity, when she could mate and produce a clutch of her own.
At the proper time, instinct had led Hesper away from her family; she had no particular end in mind, only to find her own safe space which would still provide all the food and water she needed. She had travelled through a low forest of ferns that gave her shelter, but also blocked her view of her surroundings. Sometimes a shadow had fallen over her, and she would crouch and freeze; memories of seeing her siblings being plucked from the ground and carried away by giant monsters did stick in her mind, by necessity. In the event, the shadows she had encountered had passed by quickly, and she had progressed unharmed.
For now, she had made her home in a grove of cycads, some distance from the flooded areas of the plains where adults of her kind tended to cluster. The relatively tall plants towered around her; she had been born in a place like this, and it gave her a comforting feeling of security. Tired of her trek, Hesper had taken a few days to shelter in this place, snapping at the insects that buzzed and crawled around her; the passing lizards that she had managed to catch had also gone down very nicely. It was yesterday evening when the heavy rain began, and the cycads had given the additional advantage of shielding her from the worst of the deluge.
The rain was never pleasant, but the aftermath always brought one highlight: the moist soil was much better for digging. Indeed, insects and worms seem to positively spring out of it. It took only a few scrapes for Hesper to find some juicy worms and crunchy beetles, and start snapping them up. Getting to her feet and shaking herself, she prepared to circle her grove in search of enough prey to fill her stomach.
But something stopped her in her tracks. She wasn’t sure what it was at first; there was just a general sense that something was different.
The first thing she registered was the noise; a far-off rumble, accompanied by the rustling of the ferns. As the noise grew louder, Hesper also recognised that the ground no longer felt stable.
Before she could work out which direction to flee in, one of those ominous shadows fell over her shelter, and something enormous descended from above, tearing the leaves asunder and sending fragments raining down around her.
Hesper shrieked in alarm, as her moment of peace was shattered by a terror that weighed nearly thirty thousand times as much as she did.

Super’s life was a simple one.
It hadn’t always been that way. When he hatched out of his egg ten years before, he was faced with the constant problem of a wide variety of predators, any one of which would happily eat him and think nothing of it. At the time, all he could do was keep as low a profile as possible. But his long-term – and unconscious – solution was to grow, and fast.
Through constant eating and successfully avoiding danger, Super – or rather, Supersaurus – was now eighty times his new-born length; and the reward was that, for the most part, he could live his life in peace. As long as he remained healthy, only the biggest carnivores could hope to touch him, and then only if they attacked in a group. Before long, he would be turning his attention to females, and tussling with other males for access to them; but until then, all that really mattered was fuelling the gigantic engine that was his body.
His head contained only slow thoughts, all that were needed for a slow life. He was not a curious beast; he liked certainty and the familiar, from the rumblings of his herd, to the sight and scent of a fresh source of food.
Super was on the edge of the herd at the moment; the biggest adults – their bodies the same colour as the soil they churned underfoot – were working their way through the ferns and other greenery that covered the plain, reaching out with their long necks and stripping the leaves as they went. With no room in the middle of the crowd, Super was left to look for suitable sustenance on his own – which was fortunate, as he spotted a very tempting patch of cycads about a hundred metres away. He cast his eyes to either side; there were no predators in sight. It was safe to move a little distance from the herd.
One squelching step at a time, Super plodded forward, his eyes fixed on the cycads. His relatively tiny head stretched out, and he began to feed: stripping and swallowing, stripping and swallowing. He pressed forward to get more, crushing one of the plants he had already fed upon.
There was movement down there – something moving quicker than Super could properly process. But a creature so tiny was of no consequence to him. You had to be of a certain size – say, an eight-metre-long Allosaurus that might try for a bite out of his flank – to really register on his radar.
He felt a small prick on one of his front feet, which merited only a low grumble of irritation. Such bumps and scrapes were an inevitable consequence of walking around on an uneven plain all day.
Mechanically, he swept his neck back and forth, hoovering up all of the luscious vegetation, all of his senses assuring him that this was a high-quality meal. Finally, he reached the opposite end of the patch, and all of the cycads sat stripped and trampled beneath his feet.
Super turned to re-join the herd, with a feeling akin to satisfaction. He could take a few moments of contemplation before moving on to the next meal.

A chunk of bark came flying at Hesper and struck her just as she was raising her arms in defence. It was enough to knock her over; waving her legs in the air as she tried to right herself, she saw the thing – like the bough of a tree, swaying from side to side –decimating the cycads. She couldn’t stay here.
Getting to her feet, she put her head down and fled – but as soon as she was clear of the cycads, a new obstacle appeared right in front of her: a thick tree trunk that hadn’t been there moments before. Before Hesper could fully process its sudden existence, she jumped back as it shifted towards her, ploughing up the soil before it – something tree trunks never did in her experience.
In her confusion and desperation to get to safety, Hesper leapt at the object, sinking her needle teeth into it. Her bite barely penetrated the tough skin, and failing to gain a purchase, she fell on her back.
As the object she had attacked flew upwards and away, she found herself directly in the shadow of the doom-bringer, as it shut out the sun more suddenly than any storm. Hesper heard mighty but indecipherable gurgling and rumbling sounds emanating from the scaly ceiling above her. The sun blotted out, the ground shaking, a cacophony in her ears and danger seeming to appear from every direction – how could the world have shattered so quickly?
Seeing movement out of the corner of her eye, she realised that another of the great tree trunks was swinging in her direction, and was going to come down right on top of her.
She flung herself forward with her arms and managed to get to her feet, darting away just quickly enough to avoid her tail being crushed. She felt the impact behind her, and only just succeeded in keeping her balance.
Now Hesper ran. It was all she could do, earth tremors be damned. She plunged through the foliage, keeping her head down as she sprinted. She bore no mind to what direction she was going in; all she cared about was putting distance between herself and the source of her terror. The possibility of running headlong into some other hostile monster never crossed her mind.
Finally, when her breath became too rapid and the pain in her chest too great, she brought herself to a stop to get her bearings. The sun was back, its light bathing her feathers. The ground was stable again. The ferns surrounded her protectively. Hesper thought she could make out quiet rumbling from far off, but it no longer posed an immediate threat.
She was safe again.
She did not dare settle down, but remained upright as her heart rate slowed, still anxious and poised to flee. It was still early in the day, after all, and more danger could appear at any time.
But Hesper couldn’t let that distract her from her priorities. She needed to refill her stomach after that expenditure of energy, and then find a drink of water.
A lizard scuttled across the ground directly in front of her. Instantly forgetting the horrors of a few moments ago, she lunged after it.
