blow the place up。。。。〃
〃Ssssh;〃 Levine hissed angrily; shaking his head。 He turned back to the parasaurs。 This was no time to be interrupted by a vulgar young fool。 Several of the animals bent their heads down; and began to lick the puddles of urine。 No doubt they wanted to recover lost nutrients; he thought。 Perhaps salt。 Or perhaps hormones。 Or perhaps it was something seasonal。 Or perhaps …
Levine edged forward。
They knew so little about these creatures。 They didn't even know the most basic facts about their lives … how they ate; how they eliminated; how they slept and bred。 A whole world of intricate; interlocking behaviors had evolved in these long…vanished animals。 Understanding them now could be the work of a lifetime for dozens of scientists。 But that would probably never happen。 All he could hope to do was make a few conjectures; a few simple deductions that skimmed the surface of the plexity of their lives。
The parasaurs trumpeted; and headed deeper into the forest。 Levine moved forward to follow them。
〃Dr。 Levine;〃 Eddie said quietly。 〃Get on the bike。 Now。〃
Levine ignored him; but as the big animals departed; he saw dozens of tiny green dinosaurs leap chattering out into the clearing。 He realized at once what they were: Propsognathus triassicus。 Small scavenger; found by Fraas in 1913; in Bavaria。 Levine stared; fascinated。 Of course he knew the animal well; but only from reconstructions; because there were no plete skeletons of Propsognathus anywhere in the world。 Ostrom had done the most plete studies; but he had to work with a skeleton that was badly crushed; and fragmentary。 The tall; neck; and arms were all missing from the animals Ostrom described。 Yet here the propsognathids were; fully formed and active; hopping around I Ike so many chickens。 As he watched; the pys began to eat the fresh dung; and drink what was left of the urine。 Levine frowned。 Was that part of ordinary scavenger behavior?
Levine wasn't sure。。。。
He edged forward; to look at them more closely。
〃Dr。 Levine!〃 Eddie whispered。
It was interesting that the pys only ate fresh dung; not the dried remnants that were everywhere in the clearing。 Whatever nutrients they were obtaining from the dung; it must only be present in fresh specimens。 That suggested a protein or hormone that would degrade over time。 Probably he should obtain a fresh sample for analysis。 He reached into his shirt pocket; and withdrew a plastic baggie。 He moved among the pys; which seemed indifferent to his presence。
He crouched down by the nearest dung pile; and reached slowly forward。
〃Dr。 Levine!〃
He glanced back; annoyed; and in that moment one of the pys leapt forward and bit his hand。 Another jumped onto his shoulder and bit his car。 Levine yelled; and stood up。 The pys hopped onto the ground and scampered away。
〃Damn it!〃 he said。
Eddie drove up on the motorcycle。 〃That's enough;〃 he said。 〃Get on the damn bike。 We're getting out of here。〃
Nest
The red Jeep Wrangler came to a stop。 Directly ahead; the game trail they had been following continued through the foliage; to a clearing beyond。 The game trail was wide and muddy; trampled flat by large animals。 They could see large; deep footprints in the mud。
From the clearing; they heard a low honking noise; like the sound of very large geese。 Dodgson said; 〃Okay。 Give me the box。〃
King didn't answer。
Baselton said; 〃What box?〃
Without taking his eyes off the clearing; Dodgson said; 〃There's a black box on the seat beside you; and a battery pack。 Give them to me。〃
Baselton grunted。 〃It's heavy。〃
〃That's because of the cone magnets。〃 Dodgson reached back; took the box; which was made of black anodized metal。 It was the size of a shoebox; except it ended in a flaring cone。 Underneath was mounted a pistol grip。 Dodgson clipped a battery pack to his belt; and plugged it into the box。 Then he picked the box up by the pistol grip。 There was a knob at the back; facing him; and a graduated dial。
Dodgson said; 〃Batteries charged?〃
〃They're charged;〃 King said。
〃Okay;〃 Dodgson said。 〃I'll go first; into the nest area。 I'll adjust the box; and get rid of the animals。 You two follow behind me; and once the animals are gone; you each take an egg from the nest。 Then you leave; and bring them back to the car。 I'll e back last。 Then we all drive off; Got it?〃
〃Right;〃 Baselton said。
〃Okay;〃 King said。 〃What kind of dinosaurs are these?〃
〃I have no fucking idea;〃 Dodgson said; climbing out of the car。 〃And it doesn't make any difference。 Just follow the procedure。〃 He closed the door softly。
The others got out quietly; and they started forward; down the wet trail。 Their feet squished in the mud。 The sound from the clearing continued。 To Dodgson; it sounded like a lot of animals。
He pushed aside the last of the ferns and saw them。
It was a large nesting site; with perhaps four or five low earthen mounds; covered in grasses。 The mounds were about seven feet wide; and three feet deep。 There were twenty beige…colored adults around the mounds…a whole herd of dinosaurs; surrounding the nesting site。 And the adults were big; thirty feet long and ten feet high; all honking and snorting;
〃Oh; my God;〃 Baselton said; staring。
Dodgson shook his head。 〃They're maiasaurs ; he whispered。 〃This is going to be a piece of cake。〃
Maiasaurs had been named by paleontologist Jack Horner。 Before Horner; scientists assumed that dinosaurs abandoned their eggs; as most reptiles did。 Those assumptions fitted the old picture of dinosaurs as cold…blooded; reptilian creatures; Like reptiles; they were thought to be solitary; murals on museum walls rarely showed more than one example from each species … a brontosaurus here; a stegosaurus or a triceratops there; wading through the swamps。 But Horner's excavations in the badlands of Montana provided clear; unambiguous evidence that at least one species of hadrosaurs had engaged in plex nesting and parenting behavior。 Horner incorporated that behavior in the name he gave these creatures: maiasaur meant 〃good…mother lizard。〃
Watching them now; Dodgson could see the maiasaurs were indeed attentive parents; the big adults circling the nests; moving carefully to step outside the shallow earthen mounds。 The beige maiasaurs were duck…billed dinosaurs; they had large heads that ended in a broad; flattened snout; rather like the bill of a duck。
They were taking mouthfuls of grass; and dropping it on the eggs in the mounds。 This was; he knew; a way to regulate the temperature of the eggs。 If the huge animals sat on the eggs; they would crush them。 So instead they put a layer of grass over the eggs; which trapped heat and kept the eggs at a more constant temperature。 The animals worked steadily。
〃They're huge;〃 Baselton said。
〃They're nothing but oversized cows;〃 Dodgson said。 Although the maiasaurs were large; they were plant…eaters; and they had the docile; slightly stupid manner of cows。 〃Ready? Here we go。〃
He lifted the box like a gun; and stepped forward; into view。
Dodgson expected a big reaction when the maiasaurs saw him; but there was none at all。 They hardly seemed to notice him。 One or two adults looked over; stared with dumb eyes; and then looked away。 The animals continued to drop grass on the eggs; which were pale white; oval; and nearly two feet long。 Each was about twice the size of an ostrich egg。 About the size of a small beach ball。 No animals had hatched yet。
King and Baselton stepped out; and stood beside him in the clearing。 Still the maiasaurs ignored them。
〃Amazing;〃 Baselton said。
〃Fine for us;〃 Dodgson said。 And he turned on the box。
A continuous; high…pitched shriek filled the clearing。 The maiasaurs immediately turned toward the sound; honking and lifting their heads。 They seemed agitated; confused。 Dodgson twisted the dial; and the shriek became higher; ear…splitting。
The maiasaurs bobbed their heads; and moved away from the painful sound。 They clustered at the far end of the clearing。 Several of the animals urinated in alarm。 A few of them moved away into the folliage; abandoning the nest。 They were agitated; but they stayed away。
〃Go now;〃 Dodgson said。
King stepped into the nearest nest; and grunted as he picked up an egg。 His arms hardly reached around the huge oval。 The maiasaurs honked at him; but none of the ' adults moved forward。 Then Baselton went into the nest; took an egg; and followed King back to the car。
Dodgson walked backward; holding the box on the adults。 At the edge of the clearing; he turned the sound off。
At once the maiasaurs came back; honking loudly and repeatedly。 But as they returned to the nests; it seemed as if the adults forgot what had just happened。 Within a few moments; they ceased honking; and went back to dropping grass over the eggs。 They ignored Dodgson as he left and headed back along the game trail。
Stupid animals; Dodgson thought; as he went to the car。 Baselton and King were setting the eggs into big Styrofoam containers in the back; and fitting the foam packing around them carefully。 Both men were grinning like kids。
〃That was am
